Two boxes labeled A and B are full of tickets numbered either 0 or 1 for classifying and counting. (The sum of the draws equals the number of 1's in the draws and the average of the draws equals the proportion of 1's in the draws.) We know that in Box A, 36% of the tickets are labeled 1. We also know that in Box B, 10% of the tickets are labeled 1. We will draw at random with replacement 400 times from Box A. Independently, we will draw at random with replacement 400 times from Box B. Required:
The sum of 400 draws expected value equals
