A newspaper article reported that 72% supported the 10–2 verdict. Suppose that the sample size for this survey was...

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...

What is the probability that in a group of three people at least two will have the same birth month? (Assume that all sequences of three birth months are equally likely.) (b) What is the probability that in a group of n people, n ≤ 12 , at least two will have the same birth month? (c) What is the probability that in a group of n people, n > 12 , at least two will have the same birth...

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

The length of time, in hours, it takes an "over 40" group of people to play one soccer match is normally distributed with a mean of 2.2 hours and a standard deviation of 0.55 hours. A sample of size n = 80 is drawn randomly from the population. Find the probability that the sample mean is between 2.1 hours and 2.4 hours.
