ANSWER

The correct answer is C

EXPLANATION

The conditional probability, P(A|B) means,, probability of A given that B has occurred.

It is given by the formula:P(A|B)=\frac{P(A\cap B)}{P(B)}

From the Venn diagram, A\cap ={Ian,Ella} and B={Lan,Ella,Micky,Mai, Marcus}

P(A\cap B)=\frac{2}{10} and P(B)=\frac{5}{10}

This implies that:

P(A|B)=\frac{\frac{2}{10} }{\frac{5}{10} } =\frac{2}{10}\times\frac{10}{5}=\frac{2}{5}

The correct answer is C
