Given a group of four people, find the probability that: (a) at least two have the same birth month (b) at least two have the same birthday Assume each day or month is equally likely. Ignore leap years. [Hint: First calculate the probability that they all have different birthdays. Similar to Q5 but with either 12 or 365 hotels.]

Answer to a) should be 0.427

Answer to b) should be 0.00164

BACKGROUND: Given a group of 'n' people, the odds that at least two people have the same birthday are much higher than you would think. PLEASE WRITE CODE IN C++ The program takes no input. Assumptions: 1. There is an equal chance of birthday landing on any day of the year. 2. We are not considering a leap year (only 365 days) The simulation will be run in the following manner: 1. For a group size 2, assign a random...

The birthday problem considers the probability that two people in a group of a given size have the same birth date. We will assume a 365 day year (no leap year birthdays). Code set-up Dobrow 2.28 provides useful R code for simulating the birthday problem. Imagine we want to obtain an empirical estimate of the probability that two people in a class of a given size will have the same birth date. The code trial = sample(1:365, numstudents, replace=TRUE) simulates...
