Ellen must take 4 courses this semester. She has a list of 6 math courses and 5 science
courses to from which to choose.
(a) Initially Ellen is under the impression that she can simply take any four of the courses on
the list. If this was the case, how many different ways could Ellen select the four courses?
(b) Ellen's boyfriend tells her that he thinks that she must choose 2 math courses and 2
science courses to meet her degree requirements. If this is true, how many different ways
can she select the four courses?
(c) Ellen's speaks to her advisor and finds out that her program actually only requires that at
least one of her four courses be a math course. Knowing this, how many different ways can
she select the four courses?

Use the simplex method to find the maximum value of
P = 16x + 7y + 10z
subject to these
constraints:
12x + 6y + 6z ≤ 960
24x + 6y + 6z ≤ 1500
8x + 8y + 4z ≤ 900
4x + 2y + 4z ≤ 400
and the usual constraints x ≥ 0, y ≥ 0, z ≥ 0
The maximum value of P is and this occurs when x = and y = and z = .
There is one slack variable with a non-zero value when the optimal solution is achieved. This
slack variable is the slack variable introduced in constraint number in the list of constraints
(above), and the value this slack variable has when the optimal solution is achieved is .

Bill and Sue are playing a game they call Fuddleball. To win a game a player must score 2
consecutive points or a total of 3 points altogether. Draw a tree diagram to represent all the
possible outcomes for their game of Fuddleball in which your tree records the winner of each
point.
How many outcomes are there in your tree?
How many outcomes are there in which the winner of the first point ends up losing the
game?

If people are classified by height into 7 different catagories, by weight into 4 different
catagories, by eye color into 3 catagories, by sex into 2 catagories, and by ethnic group into
5 catagories, then how many different categories of people are there if people are classified
according to all of the above?
