1. If a person bought 1 share of Amazon stock within the last year, what is the probability that the stock on that day closed at less than the mean for that year? Hint: You do not want to calculate the mean to answer this one. The probability would be the same for any normal distribution.

The probability is 50%, because for a normal distribution, one half of the probability lies below the mean.
