Binomial and Normal Review 1. Suppose we flip a coin, and we are interested in how many times the coin comes up heads. A) Which probability distribution is this an example of? Explain. B) Suppose we flip our coin 100 times. What is the mean and standard deviation of this distribution? C) Calculate the following probabilities, where X is the number of Heads on 100 flips: i) P(X = 50) ii) P(X 55)
