Practice Questions

Question 1

If event A occurs with a probability of $0.3$ and event B occurs with a probability of $0.4$, what is the probability that either event A or event B occurs if they are mutually exclusive?

Question 2

What is the probability of event A not occurring if the probability of event A occurring is $0.25$?

Question 3

If the probability of event A is $0.6$ and event B is independent from event A with a probability of $0.5$, what is the probability that both event A and event B occur?

Question 4

Event X occurs with a probability of $0.4$ and is mutually exclusive with event Y, which occurs with a probability of $0.2$. What is the probability that at least one of the events occurs?

Question 5

If the probability of event A is $0.7$, what is the probability of event A occurring at least once in two independent trials?
