Question

What is the probability of flipping three coins and having two coins land on heads and one coin land on tails?

Answer 1

You multiply the probability of each outcome.

probability of coin1 heads up: $\frac{1}{2}$
probability of coin2 heads up: $\frac{1}{2}$
probability of coin3 tails up: $\frac{1}{2}$

probability of coin1 heads, coin2 heads, and coin3 tails: $\frac{1}{2}$× $\frac{1}{2}$× $\frac{1}{2}$

=$\frac{1}{8}$

convert to a percent if needed.
