eadiness TestA store sells three varieties of cheese-cheddar, Gouda, and Swiss. Each variety of cheese is available in two different styles-shredded or sliced. If Ryan buys 120 random cheeses for a large work party, about how many of them would you expect to be shredded Gouda?60402420

Answer 1

Answer:

20

Explanation:

We are told that there are 3 types of cheese and 2 different types (sliced or shredded); therefore, the probablity of picking shredded ( probablity of 1/2) gouda (probablity of 1/3) is

$\frac{1}{3}\cdot\frac{1}{2}=\frac{1}{6}$

Now, if we pick 120 random cheeses, then the number of shredded gouda we expect to have are

$\frac{1}{6}\cdot120$$=20$

Hence, if Ryan buys 120 random cheeses for a large work party, we expect 20 of them to be shredded gouda.
