Question

In a box you have 10 triangle shaped pieces of cheese(4 white ,6 yellow) and 12 round shape pieces of cheese (7 white,5 yellow). What is the probability you reach into the box and pull out a yellow piece of cheese, given that it is round?

Answer 1

Answer:

$\frac{5}{22}$

Step-by-step explanation:

In total there are 22 pieces of cheese, 10 triangles and 12 round.

Of the round pieces of cheese, 5 are yellow. This means that the chance of choosing a round piece of yellow cheese would be $\frac{5}{22}$
