Penelope wants to look at the drinking and eating preferences of people in an attempt to create some good combinations of product sales. She looks at three drinks: Coke, Dr. Pepper, and Sprite. She looks at 2 types of snacks: Pretzels and Potato Chips.  She creates all the possible pairings of drinks and snacks and then samples 1000 individuals to determine how often they choose the combinations.  The frequencies of each of the combinations were used to calculate the probabilities that you see below in relation to the outcomes of drinks and snacks.

She finds the probability of each of these below as follows:

P(Coke) = 0.40

P(Dr. Pepper) = 0.35

P(Sprite) = 0.25

P(Pretzels) = 0.45

P(Potato Chips) = 0.55

P(Coke & Potato Chips) = 0.30

P(Coke & Pretzels) = 0.10.

Using the information provided above, calculate the following probability:

P(Potato Chips|Coke)?

P(Pretzels|Coke)?

If you know that a person is drinking coke, which snack are they more likely to grab? Potato Chips or pretzels
