14.Probability
easy
નીચે આપેલા કોષ્ટકમાં ખાલી જગ્યા ભરો :
$P(A)$ | $P(B)$ | $P(A \cap B)$ | $P (A \cup B)$ |
$0.5$ | $0.35$ | ......... | $0.7$ |
Option A
Option B
Option C
Option D
Solution
Here, $P ( A )=0.5$, $P ( B )=0.35$, $P (A \cup B)=0.7$
We know that $P (A \cup B)= P ( A )+ P ( B )- P (A \cap B)$
$\therefore 0.7=0.5+0.35- P (A \cap B)$
$\Rightarrow P (A \cap B)=0.5+0.35-0.7$
$\Rightarrow P (A \cap B)=0.15$
