Isabelle has a choice of 3 colors of pants, 5 colors of shirts, and 3 kinds of shoes. How many different outfits can she wear?
a. 12 c. 22
b. 11 d. 4
b.11
To find the total number of different outfits that Isabelle can wear, we need to multiply the number of options for each category (pants, shirts, and shoes).
First, we have 3 choices for pants. Then, for each choice of pants, we have 5 choices for shirts. Therefore, the number of outfits considering only pants and shirts will be 3 x 5 = 15.
Finally, for each combination of pants and shirts, we have 3 choices for shoes. So, we need to multiply the number of outfits we found already (15) by 3 to include the shoe options: 15 x 3 = 45.
Therefore, Isabelle can wear 45 different outfits.
The correct answer is not among the given options.
