Thus, the probability of exactly 8 heads in 10 tosses is P(X=8) = (10 choose 8)/210 = 45/1024 ≈ 0.044.
How many outcomes of 10 coin flips?
1024
How many different sequences of heads and tails are possible if you flip a coin 10 times? Answer Since each coin flip can have 2 outcomes (heads or tails), there are 2·2·... 2 = 210 = 1024 ≈ 1000 possibile outcomes of 10 coin flips.
What are the odds of flipping 11 heads in a row?
What is the probability of getting exactly 10 heads when tossing 20 coins?
( 1 2 ) n . So we have: a) Pr ( exactly 9 heads ) = ( 20 9 ) ( 1 2 ) 20 = 20995 131072 ≈ 0.1602 . b) Pr ( exactly 10 heads ) = ( 20 10 ) ( 1 2 ) 20 = 46189 262144 ≈ 0.1762 .
What is the probability of 10 heads?
While incredibly unlikely, there is still a 0.0977% chance of getting 10 heads in a row.

While incredibly unlikely, there is still a 0.0977% chance of getting 10 heads in a row.
What are the odds of getting 9 heads in a row?
1 in 512
Getting 9 heads in a row would be a probability of 1 in 512. Getting 9 tails in a row has the same probability. Thus, the chance of one OR the other is 2 in 512 or 1 in 256.
Frequently Asked Questions
How rare is 8 heads in a row?
The fair coin is tossed 8 times. P(H)=1/2 and P(T)=1/2 every toss. The probability of getting 8 heads is (1/2)^8=1/256.
How rare is it to get heads 5 times in a row?
When tossing a fair coin, the probability of getting a head is 0.5, and the probability of getting a tail is also 0.5. The outcome of each toss is independent of the others. Therefore, the probability of getting 5 heads in 5 coin tosses is 0.03125 or 3.125%.
How rare is it to get heads 10 times in a row?
Junho: According to probability, there is a 1/1024 chance of getting 10 consecutive heads (in a run of 10 flips in a row). However, this does not mean that it will be exactly that number.
What is the probability of getting 4 heads if a coin is tossed 4 times?
6.25%
When you toss a fair coin 4 times, the probability of getting 4 heads in a row is calculated by multiplying the individual probabilities together. So, the probability of getting 4 heads in 4 tosses is 0.5 * 0.5 * 0.5 * 0.5, which equals 0.0625 or 6.25%.
What's the chance of getting 4 heads in a row?
1/16
This means the probability of landing all 4 heads in 4 tosses is 1 out of the 16. So the answer is 1/16.
What are the odds against flipping a coin four times and obtaining heads all four times?
6.25%
Answer and Explanation:
The probability of getting heads on any single flip of a coin, as long as it is a fair coin, is 0.5. We can therefore find the probability of getting four heads in a row as follows. Thus, there's a 6.25% chance of getting four heads in a row.
FAQ
- How many possible outcomes when a coin is tossed 4 times?
- 16 possible outcomes Four Flips Suppose we flip a coin four times. Since each flip can come up heads or tails, there are 16 possible outcomes, tabulated below, grouped by the number of heads in the four flips. Number of Ways summarises how many different ways the results of the four flips could end up with a given number of heads.
- What is the probability of 5 heads in a row?
- Question: What is the probability of obtaining five heads in a row when flipping a coin? Interpret this probability. The probability of obtaining five heads in a row when flipping a coin is 03125. (Round to five decimal places as needed.)
- What are the odds of getting 5 tails in a row?
- Summary: A coin is tossed 5 times. The probability that all 5 tosses are tails is 1/32.
- What is the probability you get 5 heads if you flip a coin 5 times?
- So the probability that you get either heads or tails is 0.5. So that would just be 0.5 to the fifth. Power. 5 choose 4 is just 5. And that's 5 times 0.5 to the fifth.
- What is the probability of flipping 5 heads in a row when flipping a coin?
- A fair coin is one that has the probability 1/2 to come up tails when tossed and 1–1/2=1/2 to come up heads. The probability of obtaining 5 heads or 5 tails or a heads + b tails in a row with a+b=5 is always (1/2)^5=[(1/2)^a][(1/2)^b]=1/32=0.03125= 3.125%. In fact the number of outcomes: [TTTTT]+[HTTTT]+…..
- What are the odds of getting heads 50 times in a row?
- For 50 flips, your chances of heads all 50 times is 8.8817842^-16%. This gives you a roughly 1 in 100,000,000,000,000 (one quadrillion) chance of flipping all heads.
What are the odds of five heads in a row
What is the probability of getting 50 heads? | Wikipedia writes For example, suppose a fair coin is flipped 100 times. Using the law of averages, one might predict that there will be 50 heads and 50 tails. While this is the single most likely outcome, there is only an 8% chance of it occurring. |
What are the odds of getting 100 heads in a row? | The probability of obtaining 100 heads as a result of flipping a fair coin 100 times is 1/(2^100) = 1/1267650600228229401496703205376 (1 on 1 nonillion 267 octillion 650 septillion 600 sextillion 228 quintillion 229 quadrillion 401 trillion 496 billion 703 million 205 thousand 376). |
Is flipping a quarter really 50 50? | A flipped coin has a 50.8 per cent chance of landing on the same side up as when it was flipped, and a 49.2 per cent chance of landing the other way up. |
What is the probability of getting all heads if you flip a coin 4 times? | 1/16 Answer: If you flip a coin 4 times, the probability of getting all heads is 1/16. |
What is the probability of 4 heads in 5 coin flips? | There are 32 possible outcomes: 2⁵ (2 because flipping a coin has 2 possible outcomes, 5 because there are 5 flips). There are 5 outcomes that meet your criteria: HHHHT, HHHTH, HHTHH, HTHHH, and THHHH. Therefore, the chances are 5/32 that you get 4 heads out of 5 flips. That's 15.625%. |
What are the odds of winning coin flip 4 times? | 1/16 The probability is therefore 1/16. N=4: There is only one possible outcome that gives 4 heads, namely when each flip results in a head. The probability is therefore 1/16. |
- What is the probability of getting exactly 5 heads?
- 24.6% Number of possible outcomes = 2^10 = 1,024. Number of ways you can get exactly 5 heads is (10*9*8*7*6)/(1*2*3*4*5) = 252. Probability of getting exactly 5 heads = 252/1,024 = 24.6%.
- What are the odds of flipping 20 heads in a row?
- Since a run of 20 heads is roughly a one-in-a-million occurence, a basic feel for probability should tell you that trying to do this a million times is not going to be a certainty - fairly far from it.
- What are the odds of flipping 9 heads in a row?
- 1 in 512 Getting 9 heads in a row would be a probability of 1 in 512. Getting 9 tails in a row has the same probability. Thus, the chance of one OR the other is 2 in 512 or 1 in 256.
- What are the odds of getting 12 heads in a row?
- 0.000244 Similarly, there is only one way to have all 12 flips land on heads, because if any of them were not a head, then it would not be all heads, so the probability of getting all heads is the same as the probability of getting all tails. That is, it is 1 divided by 4096, or , which has an approximate value of 0.000244.
- Is flipping a coin really 50 50?
- According to a recent study led by researchers at the University of Amsterdam, coin tosses are not as random as we thought, and there may be a slight bias towards the side that starts facing up. The side of the coin that is facing up before the toss has a higher chance of facing up when the coin lands.
