Question

Are these outcomes mutually exclusive? Why? No. Choosing a yellow and red M&M; is not possible. Yes. Choosing a yellow and red M&M; is possible. Yes. Choosing a yellow and red M&M; is not possible. No. Choosing a yellow and red M&M; is possible. (c) Find P(not purple candy). According to a survey, 62% of adults are concerned that Social Security numbers are used for general identification. For a group of eight adults selected at random, we used Minitab to generate the binomial probability distribution and the cumulative binomial probability distribution (menu selections Calc Probability Distributions Binomial). (a) Find the probability that out of eight adults selected at random, at most five are concerned about Social Security numbers being used for identification. Do the problem by adding the probabilities P(r = 0) through P(r = 5). (Round your answer to three decimal places.) Is this the same as the cumulative probability P(r lessthanorequalto 5)? Yes No (b) Find the probability that out of eight adults selected at random, more than five are concerned about Social Security numbers being used for Identification. First, do the problem by adding probabilities P(r = 6) through P(r = 8). (Round your answer to three decimal places.) Now do the problem by subtracting the cumulative probability P(r lessthanorequalto 5) from 1. (Round your answer to three decimal places.) Do you get the same results? Yes No A company is in the business of finding addresses of long-lost friends. The company claims to have a 70% success rate. Suppose that you have the names of five friends for whom you have no addresses and decide to use the company to track them. (a) Make a histogram showing the probability of r = 0 to 5 friends for whom an address will be found.

Explanation / Answer

a) adding all of above :=P(r=0)+P(r=1)+P(r=2)+P(r=3)+P(r=4)+P(r=5)=0.641

YEs

b) required probabilty =P(r=6)+P(r=7)+P(r=8) =0.359

Yes
