HELP PL According to a survey, 51% 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 Plr = 0) through Pr = 5). (Round your answer to three decimal places.)
Is this the same as the cumulative probability Prs 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 Pr = 6) through Pr = 8). (Round your answer to three decimal places.)
Now do the problem by subtracting the cumulative probability Pr 55) from 1. (Round your answer to three decimal places.)
Do you get the same results?
Yes
O No
