Explanation Given Information: The man can sell 180 umbrellas if it rains hard. The man can sell 50 if it rains lightly. The man can sell 10 if it doesn’t rain at all. Past records show that it rains hard 25 % of the time. Past records show that it rains lightly 20 % of the time. Past records show that it doesn’t rain at all 55 % of the time. Umbrellas cost $4 each and the unsold ones are returned at $2 each. Explanation: Consider the provided data, The man can sell 180 umbrellas if it rains hard. The man can sell 50 if it rains lightly. The man can sell 10 if it doesn’t rain at all. Past records show that it rains hard 25 % of the time. Past records show that it rains lightly 20 % of the time. Past records show that it doesn’t rain at all 55 % of the time. Umbrellas cost $4 each and the unsold ones are returned at $2 each. Out of the 3 options available if the man buy 0 umbrellas, There will be no profit. Consider the man buys 100 umbrellas. For a discrete random variable x with values x 1 , x 2 , … , x n , then the expected value of x that is the mean of the distribution, μ Is defined as, μ = E ( x ) = ∑ [ x Pr ( x ) ] = x 1 Pr ( x 1 ) + x 2 Pr ( x 2 ) + ⋯ + x n Pr ( x n ) So, the expected profit is. μ = [ 4 ( 100 ) ( 0
