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: x 0 1 2 p(x) 0.28 0.37 0.22 0.08 0.05 calculate and interpret ox 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 1.208; if we were to select many boxes bulbs randomly, the number of defective bulbs would typically vary about 1.208 from the mean
