Step-by-step explanation:

To get the probability that student got A given that they are male, we will apply conditional probability:


\begin{gathered} P(A\text{ / B) = }\frac{P(A\text{ }\cap\text{ B)}}{P(B)} \\ \text{where A = student got A} \\ B\text{ = males} \end{gathered}
\begin{gathered} P(A\text{ }\cap\text{ B) = the value co}mmon\text{ to both A and male} \\ \text{The intersection of getting A and male} \\ P(A\text{ }\cap\text{ B) = 2} \\ \\ P(B)\text{ = total of males} \\ P(B)\text{ = }27 \end{gathered}
undefined
