What is the Fundamental Counting Principle?

• The product of natural numbers from "n" down to 1.

• An arrangement or lineup where order matters.

• If decision M can be made "m" ways and decision N can be made "n" ways, then the two can be made "m·n" ways.

• The probability of two mutually exclusive events.

What is the formula for a permutation?

• n!

• nPr = n! / (n-r)!

• nCr = n! / r!(n-r)!

• P(A and B) = P(A)·P(B)

What is a combination?

• An arrangement or group where order doesn't matter.

• An arrangement or lineup where order matters.

• The product of natural numbers from "n" down to 1.

• The probability of two mutually exclusive events.

What is the formula for a combination?

• n!

• nPr = n! / (n-r)!

• nCr = n! / r!(n-r)!

• P(A and B) = P(A)·P(B)

What defines independent events?

What is the formula for independent events?

• P(A and B) = P(A)·P(B)

• P(A and B) = P(A)·P(B after A occurred)

• P(B|A) = P(A and B) / P(A)

• nCr = n! / r!(n-r)!
