Question

A recent survey reported that 73% of Americans approve of human embryonic stem cell research. If an American is selected at random, find the probability that he or she will disapprove or have no opinion on the issue. The probability that he or she will disapprove or have no opinion on the issue is __% .

Answer 1

27%

Explanation:

100% (total population) - 73% (people who will approve) = 27% (no opinion or disapprove)

-> We can take our whole, 100%, and subtract the portion that will approve to find the percentage (%) of people that will not approve or that will have no opinion
