14.Probability
easy

$A$ और $B$ स्वतंत्र घटनाएँ दी गई हैं जहाँ $P ( A )=0.3, P ( B )=0.6$ तो $P ( A$ और $B$ )  का मान ज्ञात कीजिए।

A

$0.18$

B

$0.18$

C

$0.18$

D

$0.18$

Solution

It is given that $P(A)=0.3,\,P(B)=0.6$..

Also, $A$ and $B$ are independent events.

$\mathrm{P}(\mathrm{A}$ and  $\mathrm{B})=\mathrm{P}(\mathrm{A}) \cdot \mathrm{P}(\mathrm{B})$

$\Rightarrow  $ $ \mathrm{P}(\mathrm{A} \cap \mathrm{B})=0.3 \times 0.6=0.18$
