As we learned

 

Conditional Probability -

Let A and B be any two events such that B\neq \phi  or

n(B) = 0 or P(B) = 0 then P\left ( \frac{A}{B} \right ) denotes the conditional probability of occurrence of event A when B has already occured

 

-

 

 P\left ( \frac{l_{M}l_{W}}{A_{M}A_{W}} \right ) =\frac{4!\cdot (2!)^{5}}{5!\cdot (2!)^{4}}=\frac{2}{5}


Option 1)

\frac{1}{2}

 

 

 

Option 2)

\frac{1}{3}

Option 3)

\frac{2}{5}

Option 4)

\frac{1}{5}
