1)In how many different ways can you roll doubles in a monopoly game when you use two die
2)caterer offers a choice of five desserts from a list of eight for the dessert bar at the prom. How many different groups of desserts could be served?

1.
Sample space = 6*6 = 36
Number of successes (doubles)
= {11,22,33,44,55,66}
=6
Figure out the probability for doubles.
2. 8 choose 5
=C(8,5)
where
C(n,r) is defined as the combination of r items chosen from n.
=n!/(r!(nr)!)
