Answer: $P\left ( A\right )=0.45$

$P\left ( B\right )=0.32$

Step-by-step explanation:

Given

$P\left ( A\cup B\right )=0.626$

$P\left ( A\cap B\right )=0.144$

and we know

$P\left ( A\cup B\right )=P\left ( A\right )+P\left ( B\right )-P\left ( A\cap B\right )$

$0.626=P\left ( A\right )+P\left ( B\right )-0.144$

$0.77=P\left ( A\right )+P\left ( B\right )$ -------1

as it is given

A and B are independent therefore

$P\left ( A\cap B\right )=P\left ( A\right )\cdot P\left ( B\right )$

$0.144=P\left ( A\right )\cdot P\left ( B\right )$

Substitute value of $P\left ( B\right )$ in 1

$0.77=P\left ( A\right )+\frac{0.144}{P\left ( A\right )}$

on solving $P\left ( A\right )=0.45$

$P\left ( B\right )=0.32$
