Answer:

P(x > 5.3) = 0.3375

The probability that the random variable has a value greater than 5.3 is 0.3375.

Explanation:

To find the probability that the random variable has a value greater than greater 5.3, we would find the area under the density curve,

P(x > 5.3) =

Area = length * height

Area = (8-5.3) * 0.125

P(x > 5.3) = 0.3375

The probability that the random variable has a value greater than 5.3 is 0.3375.
