Multiply each of the 3 prices by the associated probability, and then add up these three products:

($48)(1/2) + ($56)(1/8) + ($72)(3/8) = $24 + $7 + $27 = $58 (answer)

The total expected value of a pair of sneakers is $58. Option D is correct

Given the prices of the three sneaker styles are $48,$56, and $72.

If the probability of choosing the $48 sneaker style is 1/2, the expected value = 1/2(48) = $24

If the probability of choosing the $56 sneaker style is 1/8, the expected value = 1/8(56) = $7

If the probability of choosing the $72 sneaker style is 3/8, the expected value = 3/8(72) = $27

The total expected value of a pair of sneakers = $24 + $7  $27

The total expected value of a pair of sneakers = $58
