An art class is making paperweights out of plaster. They use a mold in the shape of a rectangular prism. (2 1/4m, 2 1/2m, and 1 3/4m represents the size of the prism) How much plaster will it take to completely fill the mold?

Step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

the expected value of the random variable : 0, 1 and 2
