Question 1

If A and B are dependent events, then

Accepted Answer

$$P\left( {A/B} \right) = P\left( B \right) \cdot P\left( {A/B} \right)$$

Answer

$$P\left( {A/B} \right) = \frac{{P\left( A \right) \cdot P\left( {B/A} \right)}}{{P\left( A \right)}}$$

Answer

$$P\left( {A/B} \right) = P\left( A \right) \cdot P\left( {B/A} \right)$$

Answer

$$P\left( {A/B} \right) = \frac{{P\left( A \right) \cdot P\left( {B/A} \right)}}{{P\left( B \right)}}$$
