ઘટનાઓ $E$ અને $F$ માટે $\mathrm{P}(\mathrm{E})=\frac{3}{5}, \mathrm{P}(\mathrm{F})$ $=\frac{3}{10}$ અને $\mathrm{P}(\mathrm{E} \cap \mathrm{F})=\frac{1}{5} .$ છે. $E$ અને $F$ નિરપેક્ષ છે ?
Option A
Option B
Option C
Option D
Solution
It is given that $P(E)=\frac{3}{5}, \,P(F)=\frac{3}{10}$ and $P(E F)=P(E \cap F)=\frac{1}{5}$
$P(E) .P(F)=\frac{3}{5} \times \frac{3}{10}=\frac{9}{50} \neq \frac{1}{5}$
$\Rightarrow P(E). P(F) \neq P(E F)$
Therefore, $\mathrm{E}$ and $\mathrm{F}$ are not independent.
