Explanation Given Information: The percentage of Xbox players who are teenagers is 48.2 % , the players who are in their twenties 38.6 % , the players who are in their thirties 11.6 % , and the remaining are in forties. Formula Used: If n is the number of trials and X is the number of successes, then the probability for a particular value of X is given by: P ( X = x ) = C ( n , x ) p x q n − x Calculation: Consider the measurement classes of a random variable X . Evaluate the midpoint of the measurement class for teenagers, age between 10 − 19 . X = 10 + 19 2 X ≈ 15 Evaluate the midpoint of the measurement class for players in twenties, age between 20 − 29 . X = 20 + 29 2 X ≈ 25 Evaluate the midpoint of the measurement class for players in thirties, age between 30 − 39 . X = 30 + 39 2 X ≈ 35 Evaluate the midpoint of the measurement class for players in forties, age between 40 − 49 . X = 40 + 49 2 X ≈ 45 Possible values of X being a sum of two numbers are { 2 , 3 , 4 , 5 , 6 , 7 , 8 } . Evaluate the probability P ( X = 15 ) , P ( X = 15 ) = 48
