recycling probability, apply which info.
there is a study that shoat eightysix percent of people have access to curbside or drop off recycling programs. Suppose there are four people randomly selected.
what is the probability that all four have access to recycling?
what is the probability that at least one of the four does not have access to recycling?
and then if none of the four had acces to recycling, is there evidence to suggest the claim is not correct?
i know there are eighty six percent of everyone who recycle, i'm getting confused as to what information is relevant to find each question.
