2) What is a geometric probability model for Bernoulli trials? Explain and give the formulas for mean and standard deviation.
3) What is a binomial probability model for Bernoulli trials? Explain and give the formulas for mean and standard deviation.
4) What is the success/failure condition and when is it used with binomial models?
For the following questions: Tell me if this is a geometric or binomial model. Then solve the problem.
5) Assume that 13% of people are left handed. If we select 5 people at random, what is the probability that the first lefty is the fifth person chosen.
6) Assume that 13% of people are left handed. If we select 5 people at random, what is the probability that there are some lefties among the 5 people.
7) Assume that 13% of people are left handed. If we select 5 people at random, what is the probability that the first lefty is the second or third person.
8) Assume that 13% of people are left handed. If we select 5 people at random, what is the probability that there are exactly 3 lefties in the group.
9) Assume that 13% of people are left handed. If we select 5 people at random, what is the probability that there are at least 3 lefties in the group.
10) Assume that 13% of people are left handed. If we select 5 people at random, what is the probability that there are no more than 3 lefties in the group.
