In a survey of 2541 adults aged 18 years and older, 67% of
respondents claimed that it was easier to make friends in person,
whereas 33% 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? (Round your answer to
four decimal places.)
I found the answer of 0.6870 and it was incorrect. Thanks!
