Question 1054107: The birth control shot is one of the most effective methods of birth control available, and it works best when you get the shot regularly, every 12 weeks. Under ideal conditions, only 1% of women getting the shot become pregnant within one year. In typical use, however, 3% become pregnant. Choose at random 17 women using the shot as their method of birth control. We count the number who become pregnant in the next year.
A) What is the probability that at least one of the women becomes pregnant under ideal conditions? (Round your answer to four decimal places.)
B) What is the probability that at least one of the women becomes pregnant in typical use? (Round your answer to four decimal places.)

You can put this solution on YOUR website! A) Ideal: P(x >= 1) = 1 - binompdf(17, .01, 0)= 1 - .8429 = .1571
B) Typical: P(x >= 1) = 1- binompdf(17, .03, 0) =1- .5958 = .4142
