જો \(A\) અને \(B\) બે ઘટનાઓ હોય કે જેથી \(P(A)=0.7\), \(\mathrm{P}(\mathrm{B})=0.4\) અને \(\mathrm{P}(\mathrm{A} \cap \overline{\mathrm{B}})=0.5\), જ્યાં \(\overline{\mathrm{B}}\) એ \(B\) ની પૂરક ઘટના દર્શાવે છે, તો \(P(B \mid(A \cup \bar{B}))\) = __________

  1. A \(\frac{1}{4}\)
  2. B \(\frac{1}{2}\)
  3. C \(\frac{1}{6}\)

Answer & Solution

Correct Answer

(A) \(\frac{1}{4}\)

Step-by-step Solution

Detailed explanation

\begin{aligned} & \mathrm{P}(\mathrm{A})=\frac{7}{10}, \mathrm{P}(\mathrm{B})=\frac{4}{10} \\ & \mathrm{P}(\mathrm{A} \cup \overline{\mathrm{B}})=\frac{5}{10} \\ & \mathrm{P}\left(\frac{\mathrm{B}}{\mathrm{A} \cup \overline{\mathrm{B}}}\right)=\frac{\mathrm{P}(\mathrm{B}…
