A large lake is stocked with 30% catfish. You go out on the lake
to fish, and each fish you catch that is not a catfish is thrown
back into the lake. (Assume that each time you catch a fish, it is
independent of the other fish you have caught.) Let X be the number
of tries it takes until you catch your first catfish.
(a) What is the average (expected) value for X?
(b) What is the probability that...

Chapter 5: Discussions 1. Scheduling Employees: Suppose you own a catering company. You hire temporary employees to act as servers from the local college. Not being the most reliable employees, there is an 80% chance that any one server will actually show up for a scheduled event. For a wedding scheduled on a given Saturday you need at least 5 servers. (a) Suppose you schedule 5 employees, what is the probability that all 5 come to work? (b) Suppose you...

Suppose you are playing 20 hands of Texas Holdem. Let X=the number of times you get dealt a pocket pair out of your first 10 hands, and Y=the number of time you get dealt with at least one ace out of hands 11 through 20. Let Z=3X+Y. E(Z) is 5.08(i got it right) What is Variance(Z)? The correct answer is 6.25 here but I couldn't get it.
