A survey of high school juniors found that 82% of students plan on attending college. If you pick three at random, what is the p
robability that at least two plan on attending college? Round to the nearest percent. I answered the question incorrectly, thinking it was 36% but the correct answer was 91%. Can someone please tell me what I did wrong and what is the rule or process I need to take. The book never showed me any other way to solve this just this: P(x) = nCx P^x q^n-x, I just want to learn the right way to avoid mistakes again for the upcoming test.
Please and thank you
