Question

3. A fast food restaurant has the following options for toppings on their hamburgers: mustard, ketchup, mayo, onions,

pickles, lettuce, and tomato. In how many ways could a customer choose four different toppings from these
options?

Answer 1

There are 35 ways a customer can choose four different toppings from the given options.

Step-by-step explanation:

The number of ways a customer can choose four different toppings from the options of mustard, ketchup, mayo, onions, pickles, lettuce, and tomato can be found using combinations. Since the order of the toppings does not matter, we can use the formula for combinations.

We have 7 options (the toppings) and we want to choose 4 toppings. So, the number of ways is given by C(7, 4), which is equal to 35.

Answer 2

35

Step-by-step explanation:

Given that a fast food restaurant has the following options for toppings on their hamburgers: mustard, ketchup, mayo, onions, pickles, lettuce, and tomato.

A customer can choose from these 7 options 4 different options in 7C4 ways

This is because order does not matter here

So we use combinations here

Total no of ways a customer choose four different toppings from these

options=7C4

=35

Answer is 35
