Question 384951: An experiment consists of tossing a quarter, a dime, and a nickel. What is the probability that all
three coins come up the same (ie all three come up heads or all three come up tails)?

We have P(3 heads) = (1/2)^3 = 1/8. Likewise P(3 tails) = 1/8, by symmetry. The probability is 1/8 + 1/8 = 1/4.
