b. N/A

c. n=5

p=0.70

q=0.30

r: (0, 3.5)

2. There are 20 m&m’s candies in a dish. 8 are brown, three red, five green and four yellow. Two candies are picked from the dish at random. What is the probability that both are red? a. Binomial

b. P(Success) = 6/20 = 3/10

P(Failure) = 14/20 = 7/10

c. n=20

p=0.30

q=0.70

r: (0, 6)

3. A multiple choice test is given which has 10 questions. Each question has 4 choices. You did not study and have no clue as to any of the questions, so you have to randomly guess each answer. What is the probability you guess exactly 6 correctly? a. Binomial

b. P(success) = 0.00024

P(failure) = 0.99976

c. n=10

p=0.00024

q=0.99976

r: (0, 0.0024)

4. Using the information from the previous question regarding T.V. viewing and using the Binomial Table in your text: a. Find the probability that in a randomly selected group of 5 people, exactly three will say they watch less T.V. this year than last. p(x < 3) = 0.472

b. Find the probability that between 2 and 4 (inclusive) people will say they watched less T.V. this year than last year. p(2 < x < 4) = 0.936

c. Find the probability that at least one will say they watched less T.V. this year than last year. P(x > 1) = 0.969

1. In Upjohn Pharmaceutical clinical trials, 60% of those men tested remained bald after using Rogain, an anti-baldness cream. The cream will be tested on 5 men who have male pattern baldness. a. Find the probability P(r) of r successes (remaining bald) for r ranging from 0 to 5. Make a probability distribution table. r
