Explanation Given Information: The number of teenagers sampled is 40 and the probability that a randomly selected teenager shopped at a mall at least once during the next week is 0.63 . Formula used: A binomial random variable X is associated with n independent Bernoulli trials, each with a probability of success as p . The expected value of the random variable X can be computed using the formula, μ = n p Calculation: Consider the random variable X , the number of teenagers in a group of 40 who would shop at a mall during the next week. The random variable is a Binomial random variable with success as a teenager will shop at a mall during the next week
