Question

1. A bowl of Halloween candy contains 20 KitKats and 35 Snickers. You are getting ready to grab 2 pieces of candy from the bowl without looking. Create a probability distribution where the random variable, x, represents the number of Snickers picked. (You can treat the probabilities as with replacement).

Answer 1

X                             P(X)

0                              0.1322

1                              0.4628

2                              0.4050

P(X = 0) = 20/55 * 20/55 = 0.1322

P(X = 1) = 20/55 * 35/55 + 35/55 * 20/55 = 0.4628

P(X = 2) = 35/55 * 35/55 = 0.4050
