Sam 'Vandelay" Johnson plays basketball for his college team. You've observed that the probability of Sam making a given shot is 0.5 and that the success of a given shot is independent of other shots. Over the course of many games, Sam takes 90 attempted shots at the basket. Let W be the random variable that is the number of successful shots. You should use the normal approximation to the binomial to calculate the probabilities in parts b) and c). Give your answers as decimals to 4 decimal places. a) Find the probability that Sam makes exactly 49 successful shots from the 90 attempts. P(W = 49) = b) Find the probability that Sam makes at most 49 successful shots from the 90 attempts. P(W
