Explanation Given: The probability that the student swims in a week is three times is 0.30 , two times is 0.45 , one time is 0.15 , and no times is 0.10 . Approach: The expected value is given as, E = a 1 p 1 + a 2 p 2 + ⋯ + a n p n ... ( 1 ) Here, a 1 , a 2 , … , a n is the number of times student goes for swim practice and p 1 , p 2 , … , p n is the probability. Calculation: Calculate the expected number. Substitute 0.30 for p 1 , 0.45 for p 2 , 0
