Explanation Given Information: A youth has a part-time job in an ice cream shop and he receives $80 for a full day and $40 for a half day and Over the last few years on an average 8 days in the month are full days and on average 14 days per month are half days. Formula used: 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 ) Calculation: Consider the provided data, A youth has a part-time job in an ice cream shop and he receives $80 for a full day and $40 for a half day So, x 1 = 80 and probability Pr ( x 1 ) = 8 30 Over the last few years on an average 8 days in the month are full days and on average 14 days per month are half days
