Let C= the number of customers to an automobile repair shop on a randomly selected day. The table gives the probability distribution of C Customer=0,1,2,3,4,5,6,7
Probability= 0.01,0.06,0.08,0.16,0.26,0.29,0.09, 0.05
A. Verify that the probability distribution of C is valid
B. To be profitable, the repair shop needs to have at least four customers per day. What is the probability that the shop is profitable on a randomly selected day
C. Is C continues or discrete? Explain briefly
D. Make a histogram of the probability distribution and describe its shape
