Let x denote the number of defective light bulbs in a randomly selected 20-count box from a local hardware store. The variable x has the following probability distribution:

x01234
P(X)0.280.370.220.080.05

Calculate and interpret ?x.

A) 0.22; if we were to select many boxes of bulbs randomly, we would expect about 0.22, on average, to contain defective bulbs

B) 1.25; if we were to select many boxes of bulbs randomly, we would expect about 1.25, on average, to contain defective bulbs

C) 0.28; if we were to select many boxes of bulbs randomly, we would expect about 0.28 to have no defects

D) 1.099; if we were to select many boxes of bulbs randomly, the number of defective bulbs would typically vary about 1.099 from the mean

E) 1.208; if we were to select many boxes of bulbs randomly, the number of defective bulbs would typically vary about 1.208 from the mean
