Explain the 'Fundamental Counting Principle'.

Back

If one event can occur in m ways and a second can occur independently in n ways, then the two events can occur in m × n ways.

Front

What is the formula for calculating the probability of independent events?

Back

P(A and B) = P(A) × P(B) for independent events A and B.

What does it mean for two events to be 'independent'?

Back

The occurrence of one event does not affect the probability of the other event.
