Question

This Venn diagram shows sports played by 10 students .

Answer 1

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
