निम्नलिखित सारणी में खाली स्थान भरिए

$P(A)$ $P(B)$ $P(A \cap B)$ $P (A \cup B)$
$0.5$ $0.35$ .........  $0.7$

A

$0.15$

B

$0.15$

C

$0.15$

D

$0.15$

Solution

Here, $P ( A )=0.5$,  $P ( B )=0.35$,  $P (A \cup B)=0.7$

We know that $P (A \cup B)= P ( A )+ P ( B )- P (A \cap B)$

$\therefore 0.7=0.5+0.35- P (A \cap B)$

$\Rightarrow P (A \cap B)=0.5+0.35-0.7$

$\Rightarrow P (A \cap B)=0.15$
