The probability of flipping 91 coins and getting a head 91 times in a row is 1/291 or (1/2)91 or 4.039E-28.
The (1/2)91 is when there is exactly 91 coin tosses or n = 91.
As the number of trials increases so does the probability of at least 1 run of length 91.
The average number of coin flips to see 91 in a row is 4.951760157141521e+27

What is the probability of flipping no heads when you flip three identical coins?
The probability of flipping one coin and getting tails is 1/2. In order to find the probability of multiple events occurring, you find the product of all the events. For 3 coins the probability of getting tails 3 times is 1/8 because .5 x .5 x .5 = .125 or 1/8.
What is the probability of flipping a coin ten times and getting tails six times?

What is the probability of flipping a coin 75 times and getting tails 35 times or more?
1/2 of a chance since there are two sides to any coins it is always a half chance.
What is the probability of flipping a coin 5 times and getting 5 tails?
Assuming the coin is fair, it is (1/2)5 = 1/32.
What is the probability of flipping 6 fair coins 1 time and getting all heads?
0.015625For each coin, the probability of it coming up heads is 0.5. For six coins you multiply 0.5 by itself six times, which is 0.5 to the power of 6. This comes out to 0.015625, or about 0.016.If you work with fractions, then (1/2)^6 = 1/64, which comes out to the same decimal.
The probability of flipping a coin three times and getting two heads is?
There are 8 permutations of flipping a coin 3 times, or of flipping 3 coins one time. They are, with the permutations of two heads bolded...TTTTTHTHTTHHHTTHTHHHTHHH... thus, the probability of flipping a coin 3 times and getting 2 heads is 3 in 8, or 0.375.

You still still have a 1:2 chance of getting heads regardless of the times you flip.
What is the probability of getting exactly 8 tails in a row when flipping a coin ten times?
It is 3/1024 = 0.00293, approx.
What is the probability of flipping a coin twice and getting two heads?
The probability is 25%. The probability of flipping a coin once and getting heads is 50%. In your example, you get heads twice -- over the course of 2 flips. So there are two 50% probabilities that you need to combine to get the probability for getting two heads in two flips. So turn 50% into a decimal --> 0.5 Multiply the two 50% probabilities together --> 0.5 x 0.5 = 0.25. Therefore, 0.25 or 25% is the probability of flipping a coin twice and getting heads both times.
