The weekly gravel demand X (in tons) follows the pdf

However, the owner of the gravel pit can produce at most only 4 tons of gravel per week. Compute the expected value of the tons sold per week by the owner.

Step 1 of 2:

The weekly gravel demand X (in tons) ~exponential distribution with pdf

f(x) = (1/5)

The owner of the gravel pit can produce at most 4 tons of gravel per week.we have to compute the expected value of the tons sold per week by the owner.
