Answer 1

The Solution.

Step 1:

The total number of students that have A is:

2+4 = 6 students.

The number of Males that had A is 4.

The probability that a student who has A is a male is given as below:

`\begin{gathered} \text{prob(}A\text{ are Male) =}\frac{n\text{umber of male that had A}}{\text{Total number that had A}} \\ \\ \text{prob(A are Male)=}(4)/(6)=(2)/(3)=0.667 \end{gathered}`

Step 2:
