A pizza restaurant allows you to choose any 2 of 7 toppings. How many
2 answers:
Answer:
21
Step-by-step explanation:
You have 7 options for two toppings, to find the numer of combinatios you need to do the following:
this is because you have 7 toppings, so for the first one you are going to choose you have all the 7 options available, then for the second one, since you already picked one, you have 6 options left. This is why you multiply 7*6 =42
and finally divide by 2 to eliminate the duplicates. For example in the 42 options you have both pepperoni with ham, and ham with pepperoni, this are really the same combination just in a different order, so you must divide by two.
The answer is 21 combinations
