# Project #49777 - Statistics Binomial or Poisson and hyper-geometric distribution

1.) Thad is a 60% free throw shooter and in the championship game he took 7 free throws. What is the probability that Thad will make 5 of them? What is the probability that he makes more than 4 free throws?

2.) At one large university 35% of the population are freshmen. If there is a group of 15 students what is the probability that 10 of them will be freshmen?

3.) Suppose you are taking a multiple choice test. Each question has 5 possible answers, but only 1 is correct.

a. If there are 30 questions on the quiz what is the probability that you get 20 questions right?

b. If there are 40 questions, what is the probability that you get 24 or more right? 24 right would be a 60%.

4.) Suppose that Cola X is running a promotion. the odds of winning the promotion is 1 out of 8. If 7 bottles are selected off the shelf at random:

a.What is the probability that 3 are winners?

b.what is the probability that no more than 2 are winners?

5.)A school store averages four sales per hour for each hour they are open. Betty is schedualed to work 1:00 to 3:00.

a.) What is the probability that she gets exactly 10 customers in those two hours?

b.)what is the probability that she rings up more than 10 customers in those two hours?

6.)Tony's pizza averages 20 pizza orders per hour during the lunch period.

a.)What is the probability they will get 24 orders that day?

b.) What is the probability that they will recieve more than 24 orders that day?

Use Hypergeometric Distribution

7.) The manager of a furniture store just got a shipment of sofas and recliners. He knows there are 9 sofas and 5 recliners in the order.
