# If $P(A) = \frac{3}{5}$ and $P(B) = \frac{1}{5}$ , find $P (A \cap B)$ if A and B are independent events.

$\begin{array}{1 1} \frac{3}{25} \\ \frac{1}{5} \\ \frac{3}{5} \\ \frac{1}{25} \end{array}$

Toolbox:
• If A and B are independant events, $P(A\cap\;B)=P(A)\;P(B)$
Given $\;P(A)=\large \frac{3}{5}$ and $\;P(B)=\large \frac{1}{5}$
$\Rightarrow \;P(A\cap\;B)=\large \frac{3}{5}\times\frac{1}{5}=\frac{3}{25}$
