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.
