Calculating the Number of Ways to Choose Candy and Cookies

To calculate the number of ways to choose 1 candy and 1 cookie from the given options, we can use the concept of combinations.

Number of ways to choose 1 candy from 5 different types: This can be calculated using the formula for combinations, which is nCr = n! / (r! * (n-r)!), where n is the total number of items, and r is the number of items to choose. In this case, n = 5 and r = 1.

Number of ways to choose 1 cookie from 4 different types: Similarly, the number of ways to choose 1 cookie from 4 different types can be calculated using the same formula, with n = 4 and r = 1.

Calculation

Using the formula for combinations, we can calculate the number of ways to choose 1 candy and 1 cookie.

Number of ways to choose 1 candy from 5 different types: 5C1 = 5! / (1! * (5-1)!) = 5

Number of ways to choose 1 cookie from 4 different types: 4C1 = 4! / (1! * (4-1)!) = 4

Total Number of Ways

To find the total number of ways to choose 1 candy and 1 cookie, we can multiply the number of ways to choose 1 candy by the number of ways to choose 1 cookie.

Total number of ways to choose 1 candy and 1 cookie: Total = 5 * 4 = 20

So, there are 20 ways to choose 1 candy and 1 cookie from the given options.
