A Cape Town-based restaurant has three sources of revenue: eat-in orders, take-out orders and a bar. The daily revenue from each source is normally distributed with mean and standard deviation shown in the table: 1.Determine the probability that the revenue from the bar exceeded R1 300 on a particular day. A 0.3051 B 0.6949 C 0.8051 D 0.1949 2.Determine the minimum amount spent on eat-in orders by the top 5 percent of spenders on a particular day. A R11 574 B R13 915 C R12 027 D R11 093 3. Determine the probability that on a particular day, the restaurant generated revenues of exactly R11 699.16, R1 394.32 and R1 596.80 from the eat-in orders, take-out orders and the bar respectively. Assume that the three revenue sources are independent of each other. A 0.0298 B 0.0191 C 0.0064 D 0.8118
