6.  Experimental v. Theoretical Probability

8.  To find the Expected Value of an event, multiply the number of trials by the theoretical probability of the event.  If you flip a coin 80 times, how many heads would you expect to get?  80 flips * (.5 probability of a head)

12.  For permutations, the order of the events is important (first, second, third place)  If order is not important, then you calculate combinations instead.

36. Find P(heavy snow and school is open) Find P(school is open, given heavy snow)

37.  On 28% of days, the sky is mostly clear.  On mostly clear days, it rains 4% of the time.  On cloudy days, it rained 31% of the time.  Construct a tree diagram.  Find the probability that it rains on a day when it is mostly clear.

45.  Find the outlier

49. F Find the z score for a value of 97 Find the z score for a value of 67
