All of Dave’s customers are neighbors that have yards of about the same size. Dave charges a flat rate of $35 for mowing and trimming; $50 for mowing, trimming, and fertilizing, and $25 for just mowing. Based on experience, he determines that the probability that a randomly selected customer wants him to mow, trim and fertilize the lawn is 0.55; for those who want to trim and mow the probability is 0.15, and the rest of his customers just want him to mow. Let C = the amount Dave charges a randomly selected customer.
(a) Make a table that shows the probability distribution of C.
(b) Calculate and interpret the mean of C.
(c) Calculate and interpret the standard deviation of C.
