A recent survey reported that 58 % 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.
42% since 100% is certain while 58% will approve, which means that there is a 42% chance that they will either disapprove or have no oppinion since those are the only other options.it isnt 0% since that would mean that they would not disapprove at all but in our case theres 3 options and 1 option is 58% while the other 2 options in which were looking for make up the other 42% (100-58)
