Define the random variable x as x = number of people in the sample of 10 that have a food allergy. Find the following probabilities. (Round your answers to three decimal places.) LUSE SALT (a) P(x < 2) (b) P(x ≤ 2) (C) P(x ≥ 3) (d) P(1 ≤ x ≤ 2)
Twenty percent of the customers of a grocery store use express checkout. Consider five randomly selected customers, and let x denote the number among the five who use the express checkout. (Round your answer to three decimal places.) LA USE SALT (a) Calculate p(1), that is, P(x-1), P(1) (b) Calculate P(x ≤ 1), Pix S1) (c) Calculate (2x). (Hint: Make use of your answer from part (b).) P(2x)= (d) Calculate P(x1). P(x1)
