How do you calculate the total number of outcomes when choosing from multiple options?

Back

Multiply the number of choices for each option. For example, if there are 3 greens, 4 meats, and 5 dressings, the total combinations are 3 x 4 x 5 = 60.

What is a sample space in probability?

Back

A sample space is the set of all possible outcomes of a probability experiment.

If you flip a coin and roll a die, how many outcomes are there?

Back

A combination is a selection of items where the order does not matter.

Front

What is a permutation in probability?

Back

A permutation is an arrangement of items where the order does matter.

Front

What is the formula for calculating combinations?

Back

The formula for combinations is C(n, r) = n! / (r!(n - r)!), where n is the total number of items, and r is the number of items to choose.

Front

What is the formula for calculating permutations?

Back

The formula for permutations is P(n, r) = n! / (n - r)!, where n is the total number of items, and r is the number of items to arrange.
