The probability that the first customer orders a dessert
The total number of customers that ordered a dessert was 136 and the total number of the customers in the restaurant at that period was 600, dividing the total number of customers by the number of customers that ordered a dessert gives probability of first customer to order a dessert.
136÷600= 0.22667
The probability that the first customer will order a dessert or has ordered beef entrée
Probability of first customer ordering dessert + Probability of first customer ordering beef entree
P ordered dessert=136/600=0.22667
P ordered beef entrée=187÷600=0.31167
0.22667+0.31167=0.62334
Probability that the first customer is a female and does not order a dessert
From table 1, total number of customers of both gender that were present in the restaurant was 600 out of these total only 240 females ordered a dessert, this implies that to get the probability of the first customer is a female and does not order a dessert you get total number of females who did not order for dessert divided by total of the both gender (Degroot,Morris H and Mark J,144).
240÷600 = 0.4
Probability that the first customer is a female or does not order a dessert
The probability is achieved by summing up the probability of being a female and that of no dessert. The probability of being a female is attained by dividing the total number of females which is 280…
