I have some problems similar to this, but in the back of the book it just says answers will vary...
Could someone please break this down to me?
Given events A and B within the sample space S, the following sequence of steps establishes formulas that can be used to compute conditional probabilities. Justify each statement.
c) Therefore, P(B|A) = n(A and B)/n(S) over n(A)/n(S)
Use the results from above to find each probability in a standard deck of 52 cards.
Like this one for example:
