Favorite snacks for high school students in Durham County are as follows:
| Male | Female | |
| Fruit Loops | 12 | 13 |
| Pizza | 8 | 15 |
| Cookie Dough | 30 | 12 |
1.) If I select one student at random, what is the probability that she will prefer pizza?
2.) What would be the probability that the student prefers Pizza, given that I select a male?
3.) What is the probability that one randomly selected student will be a female or prefer cookie dough?
4.) I am randomly selecting one student. Are the event's " the student prefers cookie dough" and the event "the student is a female" mutually exclusive or not? why or why not?
5.) Now I am picking three consecutive students at random (without replacement). What is the probability that all three are female?

PROBLEM 1 It is well known that adult male heights follow a normal (Gaussian) distribution. The same is true of adult female heights. For general Canadian population in the range from 18 to 79 years of age, male height follows N(175 cm;7.5 cm), while female height follows N(162 cm; 7.5 cm). Depending on your gender, determine the following: I am (select one): O FEMALE MALE A. Make a (rough) sketch of the distribution, label it indicating the mean and your...
