Question

What is the probability of obtaining at least one tail in 5 flips of a coin?(enter the probability as a faction.)

Answer 1

First, you should find the probability of NOT getting a tail in 5 flips of coins.

`((1)/(2))^5=(1)/(32)`

After that, you should find the probability of getting at least 1 tail in 5 flips of coins.

`1-(1)/(32)=(32-1)/(32)=(31)/(32)`

Answer:

`(31)/(32)`
