Question

patricia is choosing an outfit to wear to her friends birthday party. she has 5 dresses, 4 pairs of shoes, and 7 sets of accessories. how many possible outfits can she wear?

Explanation:

Step1: Apply multiplication principle

The number of ways to choose an outfit is the product of the number of ways to choose each item.
The number of ways to choose a dress is $n_1 = 5$, the number of ways to choose shoes is $n_2=4$, and the number of ways to choose accessories is $n_3 = 7$.
The total number of outfits $N=n_1\times n_2\times n_3$.

Step2: Calculate the result

$N = 5\times4\times7=140$.

Answer:

140
