Question

When Chase goes to the cafeteria for lunch he chooses from four different types of sandwiches, three different types of fruit and five different drinks. If he wants a sandwich, piece of fruit and a drink, how many different 3 item meals can Chase choose? What is the probability that Chase selects a tuna sandwich, a kiwi and a V8 for lunch?

Answer 1

,Sandwiches = 4

Fruit = 3

Drinks = 5

His choice is = A sandwich, piece of fruit and a drink

`\begin{gathered} \text{ }^4C_1*\text{ }^3C_1\text{ }*\text{ }^5C_1 \\ =\text{ 4 }*3*5 \\ =60 \end{gathered}`

What is the probability that Chase selects a tuna sandwich, a kiwi and a V8 for lunch?

`(1)/(4)*(1)/(3)*(1)/(5)\text{ =}(1)/(60)`
