MCQ
જો $ P(AB) = P(A) P(B),P(A/B) = 1/4$ અને $P(B/A) = 1/3$ હોય, તો.....
- A$P(AB)\,\, = \,\,\frac{1}{6}$
- B$P({A' }{B' })\,\, = \,\,\frac{1}{6}$
- C$P(AB) = \,\,\frac{1}{{12}}$
- D$P({A' }{B' })\,\, = \,\,\frac{1}{{12}}$
અહિ ${\text{, }}P\left( {\frac{A}{B}} \right)\,\, = \,\,\frac{1}{4}\,\, = \,\,P(A)$
$P\left( {\frac{B}{A}} \right)\,\, = \,\,\frac{1}{3}\,\, = \,\,P(B)\,\, \Rightarrow \,P(AB)\,\, = \,\,\frac{1}{4}.\frac{1}{3}\,\, = \,\,\frac{1}{{12}}$
