making frienDs In a survey of 2541 adults aged 18 years and older, 64% of respondents claimed that it was easier to make friends in person, whereas 36% thought that it was easier to do so through social-networking sites. Assuming that these results apply to the entire adult population, what is the probability that at most 3 out of 6 adults chosen at random hold the opinion that it is easier to make friends through social-networking sites?
