Gr12 Mathematics: Ch 9.2 Tools and Techniques

What is the purpose of a Venn diagram in probability?

To organize and visualize possible outcomes of a sequence of events

To calculate the product of probabilities along the branches of a sequence

To show how events are related to one another (correct)

To determine the complementary events

What is the formula to calculate the probability of mutually exclusive events?

P(A and B) = P(A) × P(B)

P(A or B) = P(A) + P(B) (correct)

P(A) = 1 - P(B)

P(not A) = 1 - P(A)

What is the purpose of a two-way contingency table in probability?

To keep a record of the counts or percentages in a probability problem (correct)

To calculate the complementary events

To visualize the different possible outcomes of a sequence of events

To determine the sample space of an event
