Mary has three skirts, two blouses, and either black or white shoes that she likes to wear to school. How many days can she go without repeating the same combination of skirt, blouse, and shoes?

3*2*2

It’s 12

To find out how many days Mary can go without repeating the same combination of skirt, blouse, and shoes, we need to multiply the number of options for each item:

Number of skirt options = 3
Number of blouse options = 2
Number of shoe options = 2

Now, we can multiply these values together to get the total number of unique combinations:

Total number of days = Number of skirt options × Number of blouse options × Number of shoe options
= 3 × 2 × 2
= 12

Therefore, Mary can go without repeating the same combination of skirt, blouse, and shoes for 12 days.

To calculate the number of days Mary can go without repeating the same combination of skirt, blouse, and shoes, we need to multiply the number of options for each category.

Mary has three skirts, two blouses, and two options for shoes (black or white).

First, let's calculate the number of options for each category:

Number of skirt options = 3
Number of blouse options = 2
Number of shoe options = 2

To find the total number of combinations, we multiply the number of options for each category:

Total number of combinations = Number of skirt options x Number of blouse options x Number of shoe options

Total number of combinations = 3 x 2 x 2 = 12

Therefore, Mary can go without repeating the same combination for 12 days.
