Match each description to its appropriate step number in determining the probability of an event by using permutations or combinations. Substitute the n and r into the appropriate arrangement formula and expand all factorials

List all possible outcomes, making sure that the number matches the number of arrangements

Determine the probability by finding the favorable outcomes from the sample space

Determine if order is important, the total number of objects being considered, and the number of objects being chosen

Cross out any common factors, find the product of remaining factors, and simplify the resulting fraction
