The formula needed is \[\large P(A|B)=\frac{P(A\cap B)}{P(B)}\]

So all you need to do is simplify the fraction :) \[\frac{ 3 }{ 7 } \div \frac{ 7 }{ 8 } = \frac{ 3 }{ 7 } \times \frac{ 8 }{ 7 } = ? \]

you just substitute the values that is given (in the question) into the general formula (above) and then you work it out normally ^_^

we are given P(A∩B)=3/7 and P(B)=7/8 so we need to find out P(A|B) which there's a formula for that \(\color{blue}{\text{Originally Posted by}}\) @kropot72 The formula needed is \[\large P(A|B)=\frac{P(A\cap B)}{P(B)}\] \(\color{blue}{\text{End of Quote}}\)

we are given: \[ P(A∩B)=3/7 \] and \[P(B)=7/8\] We want to find : \[P(A|B) =?\] To do this, we need to use the general formula for conditional probability: \[P(A|B)=\frac{ P(A∩B) }{ P(B) } \]
