The prices of three sneaker styles are $48,$56, and $72. the probability of choosing the $48 sneaker style is 1/2. the probability of choosing the $56 sneaker style is 1/8. the probability of choosing the $72 sneaker style is 3/8 what is the expected value of a pair of sneakers? a$28 b$48 c$56 d$58

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
