Practice Questions

Question 1

What is the conditional probability of event A given event B, denoted as P(A | B)?

Question 2

In a tree diagram, if the probability of event A occurring is 0.6 and the probability of event B occurring is 0.4, what is the probability of both A and B occurring if they are independent?

Question 3

If a tree diagram shows two levels: at the first level the outcomes are A and A', and at the second level for A the outcomes are B and B', how are the probabilities represented?

Question 4

Which of the following scenarios represents sampling without replacement in a tree diagram?

Question 5
