You have inherited an ice cream truck for the summer of 2022. You will be selling ice cream from the truck every day that summer:
You have inherited an ice cream truck for the summer of 2022. You will be
selling ice cream from the truck every day that summer: 101 days in total, from Memorial Day
weekend until Labor Day weekend. This problem will step you through projecting how much ice
cream you expect to sell (as well as how much revenue you expect to make) during the summer.
a) Ice cream sales are known to be very dependent on weather. Suppose that for any
particular day, the weather is either rainy or sunny; on average, one-third of the days are
rainy and two-thirds of the days are sunny. Compute the expected number of sunny days
in Summer 2022 and the probability of there being more rainy days than sunny days in
Summer 2022. You may assume that the weather is independent between days.
