Cora is playing a game that involves flipping three coins at once. let the random variable h be the number of coins that land showing "heads." here is the probability distribution for h. find the expected value of the number of coins that land showing "heads." p(h>_2)
H=no. of heads 0 1 2 3
P(H) 0.125 0.375 0.375 0.125
