Suppose that the probability that an adult in America will watch the Super Bowl is 44%.
Each person is considered independent. We are interested in the number of adults in America
we must survey until we find one who will watch the Super Bowl.
(a) How many adults in America do you expect to survey until you find one who will watch the Super Bowl?
(Round your answer to the nearest whole number.)
(b) Find the probability that you must ask 3 people. (Round your answer to four decimal places.)
(c) Find the probability that you must ask 3 or 4 people. (Round your answer to four decimal places.)
~~~~~~~~~~~~~~~~~~~~~~~~
(b) P = = use your calculator.
(c) P = + = use your calculator.
--------------
Thus (b) and (c) are solved, answered and explained.
I left (a) unanswered, since you packed TOO many questions in one post.
