I need assistance with 2 questions – and do you know what formulas could be used in excel to solve? If I could figure out how to set it up – I think this is discrete. -Suppose we are flipping a fair coin (i.e., probability of heads = 0.5 and probability of tails = 0.5). Further, suppose we consider the result of heads to be a success. What is the mean of the binomial distribution if we flip the coin 5 times? -Suppose we are flipping a fair coin (i.e., probability of heads = .5 and probability of tails = .5). What is the probability that in a sample of 5 flips, fewer than 4 will be heads?
