sofia is trying to pick out an outfit for the first day of school. she can choose from 5 pairs of pants, 4 t - shirts, 7 sweaters or hoodies, and 2 pairs of shoes. how many different outfits does sofia have to choose from?
Answer
Explanation:
Step1: Identify the multiplication principle
To find the number of different outfits, we use the multiplication principle of counting, which states that if there are (n_1) ways to do the first task, (n_2) ways to do the second task, (n_3) ways to do the third task, and (n_4) ways to do the fourth task, then the total number of ways to do all four tasks together is (n_1\times n_2\times n_3\times n_4). Here, the tasks are choosing pants, t - shirts, sweaters/hoodies, and shoes.
Step2: Multiply the number of choices for each item
The number of choices for pants (n_1 = 5), for t - shirts (n_2=4), for sweaters or hoodies (n_3 = 7), and for shoes (n_4=2). We calculate the total number of outfits as (5\times4\times7\times2). First, calculate (5\times4=20). Then, calculate (20\times7 = 140). Finally, calculate (140\times2=280).
Answer:
280
