1. (book question - end of ch.6-24): a psychology class consists of 36 males and 48
females. if the professor selects names from the class list using random sampling,
a. what is the probability that the first student selected will be female?
b. and if a random sample of n=3 students is selected and the first two are both
females, what is the probability that the third student selected will be a male?

Igot $34 for my answer. first, multiply the amount of pizzas, (which is 4)by the cost of each pizza($5). you will get $20 for the cost of the 4 pizzas. then multiply the number of breadsticks (2) by the cost of each order of breadsticks ($2). you should get $4 for the cost of the two orders of breadsticks. then multiply the number of sodas(8) by the cost of each soda($1.50). you should get $12 for the cost of the 8 sodas. now add up the total costs of the 4 pizzas ($20), two orders of breadsticks ($2), and the 8 sodas ($12) to get $34. now divide 34 by 8 to get you answer, $4.25. therefore, each student owes $4.25 before tax
