the table describes the types of job openings available in a company.

what is the probability that experience is needed for a randomly selected job opening, given that it is for part-time work?
write the probability as a percent . round to the nearest tenth if needed. use the table to calculate a conditional probability.

the table gives the relative frequencies of recipes that contain sugar and salt, contain at least one of those ingredients, or contain neither of those ingredients.

what is the probability that a randomly selected recipe does not contain sugar, given that it contains salt?

write the probability as a percent. round to the nearest tenth if needed.

A drawer contains 12 brown socks, 8 white socks, and 2 blue socks. One sock is selected at random.  

What is the probability that the sock is blue, given that it is not brown?

Blue socks = 2

Not brown socks = 8 + 2 = 10

The probability that the sock is blue, given that it is not brown? = 2/10 = 1/5

A box of photographs contains 13 wedding photographs, 4 vacation photographs, and 8 holiday photographs. One photograph is randomly selected.  

What is the probability that the photograph is a holiday photograph, given that it is not a wedding photograph?

Holiday photographs = 8

Not a wedding photograph = 4 + 8 = 12

The probability that the photograph is a holiday photograph, given that it is  not a wedding photograph = 8/12 = 2/3

What is the probability that experience is needed for a randomly selected job opening, given that it is for part-time work?

Write the probability as a percent . Round to the nearest tenth if needed.

Experience is needed = 6 + 2 = 8

Part-time work = 6 + 8 = 14

The probability that experience is needed for a randomly selected job opening, given that it is for part-time work = 8/14 = 4/7 = 57.1%

What is the probability that a randomly selected recipe does not contain sugar, given that it contains salt?

Recipe does not contain sugar = 0.31

Contains salt = 0.67

The probability that a randomly selected recipe does not contain sugar, given that it contains salt = 0.31/0.67 = 46.3%

a. the residual plot for model 1 has a random pattern and is a good fit for the data.
