Final answer:
To calculate the number of ways you can choose one of each of the four types of doughnuts out of 13 doughnuts, we need to use the concept of combinations. The total number of ways to choose one of each type is 1 x 1 x 1 x 1 = 1. Therefore, there is only one way to choose one of each type of doughnut from 13 doughnuts.
Step-by-step explanation:
To calculate the number of ways you can choose one of each of the four types of doughnuts out of 13 doughnuts, we need to use the concept of combinations. Since there are four types of doughnuts and we need to choose one of each, we can consider this as choosing one doughnut from each type. The number of ways to choose one doughnut from each type can be calculated as the product of the number of choices for each type.
For each type of doughnut, there is only one choice, so the total number of ways to choose one of each type is 1 x 1 x 1 x 1 = 1. Therefore, there is only one way to choose one of each type of doughnut from 13 doughnuts.
Therefore, the correct answer is A) 13 ways.
