$A$ અને $B$ બે ઘટનાઓ એવા પ્રકારની છે કે $P(A) = 0.54, P(B) = 0.69$ અને$P(A \cap B)=0.35$  $P ( A \cup B )$ શોધો.  

Option A
Option B
Option C
Option D

Solution

It is given that $P ( A )=0.54$,  $P ( B )=0.69$,  $P (A \cap B)=0.35$

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

$\therefore P (A \cup B)=0.54+0.69-0.35=0.88$
