Question

If you flip three fair coins, what is the probability that you'll get all three head?

Answer 1

Answer:

P (HHH) = 1/8

Step-by-step explanation:

We want the probability of HHH

P(HHH) = P (heads and Heads and heads)

When we have an and, we multiply the probability

P(heads 1st time) * p(heads 2nd time) * P (3rd time)

The probability of a heads is 1/2

1/2 * 1/2 * 1/2

P (HHH) = 1/8
