Substitute the given numerical values into the rearranged formula P(B|A) = $P(B)P$(A|B)/P(A). For example, if $P(B) = 1/21$, P(A|B) = $4/10$, and $P(A) = 24/210$, the calculation is ($1/21 * 4/10$) / ($24/210$).

Conditions: The formula used is the rearranged Bayes identity for P(B|A).; The given probabilities must be consistent with the formula's assumptions (e.g., $P(A) > 0$).

Starting from the equality $P(A)P$(B|A) = $P(B)P$(A|B), you can solve for either conditional probability by dividing by the corresponding marginal probability. Dividing both sides by $P(B)$ isolates P(A|B), giving P(A|B) = $P(A)P$(B|A)/P(B).

Conditions: Both A and B have positive probability for the ordinary conditionals used here.; The algebraic rearrangement requires the denominators $P(B)$ and $P(A)$ to be nonzero.
