The probability of getting a hit is .343, so the probability of striking out is 1 - .343 or .657Fill in the 8 probabilities by multiplying the probabilities along the lines that lead to each outcome. For instance, the probality of H,H,H (getting 3 hits) is gotten by multiplying (.343)(.343)(.343) = .040353607 The probability of the third to last case which was O,H,O (getting an out, then a hit, then an out) is gotten by multiplying (.657)(.343)(.657) = .148055607 If you add the whole list of probabilities you should get 1.
