1. A (100% sure about this one)

2. 24% (100% sure about this one)

3. 60% (90% sure about this one because the question was confusing)

4. 41% (95% sure about this one)

Step-by-step explanation:

1.

A box of photographs contain:

13 wedding photographs

4 vacation photographs

8 holiday photographs

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

We can get a holiday or vacation photograph. It just can't be a wedding photograph so:

8 holiday photos + 4 vacation photos = 12 photos in all

The chance of getting one of those 12 is 12/25 or choice a

2.

The table describes the type of jobs 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.

Part time w/ experience: 6

Part time w/ no experience: 8

Full time w/ experience: 2

Full time w/ no experience: 9

Part time w/ experience is what we need. The chance of randomly getting it is 6/25 which is 24/100 or 24%

3.

One student from a music class is randomly selected on the first day of class. There is an 80% chance that the student arrived on time and a 20% chance that the student arrived on time and is female.

What is the probability that the chosen student is a male student, given that the student arrived on time? Write the probability as a percent. Round to the nearest tenth if needed.

There is a 20% chance that the student will be late.

There is the 20% chance in that 80% chance that the student arriving on time is female. Therefore 80%-20% is 60% which means there is a 60% chance of the student arriving on time is a male.

4.

A researcher surveyed people as they left a museum, asking whether they visited the gift shop and whether they watched the film about the museum's history. The table shows the relative frequencies of the responses. One person who was surveyed was randomly selected.

What is the probability that the person visited the gift shop, given that the person did not watch the film? Write the probability as a percent. Round to the nearest tenth if needed.

I'm too lazy to write the entire graph in words so:

41% of all the people did not watch the film but went to the gift shop.

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
