say 4 out of 10 people like cats.
given a random sample of 10 people, what is the probability that NONE of them like cats?
for some reason i'm drawing a blank here and its really pissing me off. saying 4 out of 10 people like cats is the same as saying theres a 60% chance that any given person is a NOT cat-liker, right? so in a sample of 10 people, the chance none of them likes cats is .6^10? that just doesn't feel right at all...
