a. If two people are selected at random, the probability that they do not have the same birthday (day and month) is 365/365+364/ 365 Explain why this is so. (Ignore leap years and assume 365 days in a year.)The first person can have any birthday, so they can have a birthday onof the 365 days. In order for the second person to not have the same birthday they must have one of the remaining birthdays.(Type whole numbers.)
