She is concerned 0 calls 1 call 2 calls 3 calls 4 calls 5 calls 0.15 0.10 0.05 0.25 0.30 0.15 (a) What is the expected value for the number of calls she receives? alls (b) What does your answer to part (a) mean? Each day, she can expect the average number of calls to equal the number of calls calculated in part (a). O Over the long run, she can expect the average number of calls per day to equal the number of calls calculated in part (a). O Over the long run, she can expect the total number of calls per day to equal the number of calls calculated in part (a).
