The owner of a restaurant serving Continental-style en-trees was interested in studying ordering patterns of patrons for the Friday-to-Sunday weekend time period. Records were maintained that indicated the demand for dessert during the same time period. The owner decided to study two other variables, along with whether a dessert was ordered: the gender of the individual and whether a beef entree was ordered. The results are as follows:

A waiter approaches a table to take an order for dessert. What is the probability that the first customer to order at the table
a. Orders a dessert?
b. Orders a dessert or has ordered a beef entree?
c. Is a female and does not order a dessert?
d. Is a female or does not order a dessert?
e. Suppose the first person from whom the waiter takes the dessert order is a female. What is the probability that she does not order dessert?
f. Are gender and ordering dessert independent?
g. Is ordering a beef entree independent of whether the person orders dessert?
