Find the probability of a jack when drawing a single card from a deck of 52 cards:

\frac{1}{13}

Find the probability of getting either a club and a jack when drawing a single card from a deck of 52 cards:

\frac{1}{52}

Use the Inclusion-Exclusion formula

P (X \lor Y) = P (X) + P (Y) - P (X \land Y)

= \frac{1}{4} + \frac{1}{13} - \frac{1}{52}

\frac{1}{4} + \frac{1}{13} - \frac{1}{52} = \frac{4}{13}

= \frac{4}{13}
