Question

What is the answer? PLEASE

Answer 1

Using the combination formula, the probability that Rosa's mom chooses sausage and onion is given by:

B. $\frac{1}{C_{8,2}}$.

The order in which the toppings are chosen is not important, hence the combination formula is used to solve this question.

What is the combination formula?

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

2 toppings are chosen from a set of 8, hence the number of options is given by:

$C_{8,2}$.

Sausage and onion correspond to one topping, hence the probability is given by:

B. $\frac{1}{C_{8,2}}$.
