Question
In a certain population of people, 20% will contract Disease A at some point in their lifetime, 21% will contract Disease B at some point
In a certain population of people, 20% will contract Disease A at some point in their lifetime, 21% will contract Disease B at some point in their lifetime, and 75% will not contract either of these diseases in their lifetime.
A person from this population is randomly chosen.
1) Find the probability that the person chosen contracts Disease A or Disease B
2) Find the probability that the person chosen contracts only one of these two diseases.
3) Suppose a person contracts Disease A. What is the chance that this person will contract Disease B?
4) If a person contracts Disease B, what is the probability they will also contract Disease A?
