Find the probability that the number who say cashews are their favorite nut is (a) exactly three, (b) at least four, and (c) at most two. If convenient, use technology to find the probabilities. (a) P(3) = (b) P(x ≥ 4) = (c) P(x≤2) = ... (Round to the nearest thousandth as needed.) (Round to the nearest thousandth as needed.) (Round to the nearest thousandth as needed.)
