Answer 1

Given:

The table represents the data collected at a sandwich shop for the last six months with respect to the type of bread

We will find P(cheese | wheat)

We will use the following formula:

`P(A|B)=(P(A\cap B))/(P(B))`

Let A represents cheese, and B represents wheat

From the table:

`\begin{gathered} A\cap B=1200 \\ B=1200+700=1900 \end{gathered}`

So, the probability will be as follows;

`P\left(cheese|wheat\right)=(1200)/(1900)=(12)/(19)`

So, the answer will be:

P(cheese | wheat) = 12/19 = 0.63
