Annabelle wants to move to a new city. If her chance of getting a job in Montreal is 10%, and

her chance of getting a job in Vancouver is 35%:

3a) What is the probability that Annabelle will be offered both jobs?
3b) What is the probability that she will only get one of the jobs?

3a) If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.

3b) Either-or probabilities are found by adding the individual probabilities.
