2. All of Dave's customers are neighbors that have yards of about the same size. Dave charges a flat rate of $32 for mowing and trimming and $20 for just mowing. Based on experience, he determines that the probability that a randomly selected customer wants him to mow and trim the lawn is 0.85; the rest of his customers just want him to mow. Let C= the amount Jacob 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
