Question

Two soccer players have one penalty kick each. The probability of each player scoring with a penalty kick is 0.2 and 0.3, respectively. What is the probability that at least one of them will score?
The prob(both will miss) = .8(.7) = .56

so the prob(at least one score) = 1 - .56 = .44

or

W W = (.2)(.3) = .06
W L = (.2)(.7) = .14
L W = (.8)(.3) = .24
L L = (.8)(.7) = .56

.06 + .14 + .24 = .44
