What is the probability of getting exactly 5 heads in 20 coin flips?

The probability of getting 5 heads in 20 coin flips is approximately 0.015.

What is the probability of getting exactly 5 heads in 10 coin flips?

Originally Answered: What is the probability of getting exactly 5 “heads” in 10 coin flips? 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 chances of flipping heads 30 times in a row?

That’s a lot more likely: the likelihood of getting a string of 30 heads in a row somewhere in your 100 flips is about 1 in 30 million. If there are at least 30 million people in the world who have flipped a coin 100 times, it shouldn’t be surprising if one of them has flipped 30 heads in a row at some point.

What is the probability of obtaining 12 heads in a row when flipping a coin?

The probability of obtaining twelve heads in a row when flipping a coin is 0.00024.

What is the probability of getting tails exactly 5 times?

While the probability of flipping a coin 5 times and getting a Tails every time is relatively low at 1 out of 32, it is still a reasonable possibility. The probability of the new coin flip being a tail is still one out of two or 1/2.

What is the probability that if you flipped a fair coin 12 times that you would get heads 4 times and tails 8 times?

Aditya Banerjee. Probability of getting exactly 8 heads in tossing a coin 12 times is 4954096.

What is the probability of flipping 10 heads in a row?

a 1/1024 chance
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. It might take one person less throws to get 10 consecutive heads.

How many times does a coin flip for 15 heads?

A coin is flipped 30 times. What is the probability of getting exactly 15 heads (round the answer to 4 decimal places)? Jeff Bellucci’s answer is quite complete, but I like this problem because there is an interesting approximation that can come in quite handy.

What is the most likely outcome when flipping 30 coins?

15 heads out of 30 is the most likely outcome when flipping 30 coins, if you run the same calculation with 14 or 16 heads you will get two equal, but smaller probabilities, same with 13 and 17 heads, and so on.

What is the probability of a coin with exactly n Heads?

Jeff Bellucci’s answer is quite complete, but I like this problem because there is an interesting approximation that can come in quite handy. If you flip 2 n fair coins, the probability of exactly n heads is very closely approximated by 1 π n for large n. As Jeff Bellucci points out, the true answer, rounded to four decimal places is 0.1445.

What is the relative error in probability when flipping a coin?

If you flip 2 n fair coins, the probability of exactly n heads is very closely approximated by 1 π n for large n. As Jeff Bellucci points out, the true answer, rounded to four decimal places is 0.1445. The relative error in the approximation is therefore just less than 1\%.
