14.Probability
easy
$A$ 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 $P (A \cup B)= P ( A )+ P ( B )- P (A \cap B)$
$\therefore P (A \cup B)=0.54+0.69-0.35=0.88$
