Please forgive my statistical ignorance! I have a couple of problems in my Stats class that I would like anyone to review and let me know if I am on the right track...(adsbygoogle = window.adsbygoogle || []).push({});

You have applied for a job at Store A and also Store B. You estimate the probabilities of getting the job at the stores A and B are 0.1 and 0.7 respectively. You also estimate that the probability of getting both jobs is only 0.04.

What is the probability that you get at least one of the jobs?

a) 0.04

b) 0.72

c) 0.8

d) 0.76

I chose c) 0.8 (by adding the probabilities of A and B together)

What is the probability that you will get exactly one of the jobs?

a) 0.72

b) 0.04

c) 0.76

d) 0.8

I chose c) 0.76 (by adding the probabilities of A and B together, then subtracting the probability of getting both jobs)

Could someone/anyone look at this and tell me if I am on the right track, please? I am having a terrible time trying to understand this theory! Thanks in advance for any help you can offer me.
