The probability of obtaining nine heads in a row when flipping a coin is

1 answer:

7 0

Answer: The probability is about 0.2%.

The probability of flipping heads one time is 0.5, 50% or 1/2.

To flip heads 9 times in a row, we have to multiply 1/2 by itself 9 times.

(1/2)^9 = 1/512 or about 0.2%

It should only happen once every 512 times.
