Only 36 and 38. I wrote down 35 and 33, you will need information from those exercises.

36- Four Children Using the same example space and assumption from exercise 35, find the probability that when a couple has four children, all four are of the same gender.

35- Four Children Exercise 33 lists the sample space for a couple having three children. After identifying the sample space for a couple having four children, find the probability of getting three girls and one boy (in any order).

33- Three Children Use this sample space listing the eight simple events that are possible when a couple has three children: bbb, bbg, bgb, bgg, gbb, gbg, ggb, ggg. Assume that boys and girls are equally likely, so that the eight simple events are equally likely. Find the probability that when a couple has three children, there is exactly one girl.

38- Buckle Up A study of the effect of seatbelt use in head-on passenger car collisions found that drivers using a seatbelt had a 64.1% survival rate, while drivers not using a seatbelt had a 41.5% survival rate. If seatbelts have no effect on survival rate, there is less than a 0.0001 chance of getting these results(based on data from "Mortality Reduction with Air Bag and Seat Belt Use in Head- on Passenger Car Collisions, " by Crandall, Olson, Sklar, American Journal of Epidemiology, Vol. 153, No. 3). What do you conclude?
