Question

What is the probability of achieving the result TTTTT when flipping a fair coin five times?

Answer 1

1/32

Explanation:

There are 2 possibilities when you flip a coin - heads or tails.

The probability of tails = 1/2.

The next flip is completely independent of the other flips.

So the problem is just:

(1/2) * (1/2) * (1/2) * (1/2) * (1/2) = 1/32
