Question

Deidra went to her local bakery to purchase a bagel and a cream cheese topping. Bagels come in plain, blueberry, cinnamon raisin, and garlic. The toppings are plain, chive, and sun-dried tomato. How many different combinations can Deidra choose from if she selects a bagel and a cream cheese topping?

Answer 1

Using the Fundamental Counting Theorem, it is found that Deidra can choose 12 different combinations.

What is the Fundamental Counting Theorem?

• It is a theorem that states that if there are n things, each with $n_1, n_2, \cdots, n_n$ ways to be done, each thing independent of the other, the number of ways they can be done is:

$N = n_1 \times n_2 \times \cdots \times n_n$

In this problem:

• For the bagels, there are 4 options, hence $n_1 = 4$.

• For the topping, there are 3 options, hence $n_2 = 3$.

Then:

$N = n_1n_2 = 4(3) = 12$

Deidra can choose 12 different combinations.
