Review for first half of EngageNY Module 4. Includes two-way tables, conditional probabilities, independence, and z-scores

Organize the following probilities into conditional and not conditional based on the following two-way table

1. Probability that a person gets a hot dog
2. Probability that a person gets no food given they get a soda
3. Probability a person doesn't get a drink
4. If a person has gotten pizza, probability they get water
5. Probability that a person gets both a hot dog and soda
6. A person got water, what is the probability they got pizza
7. Probability a person got a hot dog but no drink
8. Given a person got soda, probability of getting a hot dog

Conditional
Not Conditional

Find the probability for each of the probabilities above

1. Probability that a person gets a hot dog

2. Probability that a person gets no food given they get a soda

3. Probability a person doesn't get a drink

4. If a person has gotten pizza, probability they get water

5. Probability that a person gets both a hot dog and soda

6. A person got water, what is the probability they got pizza

7. Probability a person got a hot dog but no drink

8. Given a person got soda, probability of getting a hot dog

Are getting a hot dog and soda independent? Use conditional probability definition

Are getting a hot dog and soda independent? Use multiplication definition

In a school of 320 students, 85 students are in the band, 200 students are on sports teams, and 60 students participate in both activities.

Draw a Venn diagram representing this scenario.

What is the probability a student is in band but not sports?

What is the probability a student is in neither?

What is the probability of a student being in band OR sports?

The Welcher Adult Intelligence Test Scale is composed of a number of subtests. On one subtest, the raw scores have a mean of 35 and a standard deviation of 6.
