1. It takes five people working on different tasks to produce a new product. A small workplace has five

different workers and the plant manager wants to experimentally compare which workers/job

combinations produce the product in the fastest time. If they wanted to perform this experiment, how

many different combinations must they analyze?

My answer is 5 x 5 = 25.

Is that correct? Your check is needed.

2. Domino’s Pizza offers pizzas with two different sizes, three different types of crusts and up to 10

toppings. For topping you have a choice of having or not having.

How many different types of pizzas can be made?

My answer to the 2nd question is 2 x 3 x 11 = 66.

I that also correct? Your check is needed.
