Find the probability of getting jack diamond :

\frac{1}{52}

Find the probability of getting 7 club :

\frac{1}{52}

Since the events are disjoint, Use the formula

P (X_{1} \lor X_{2} \lor \dots \lor X_{k}) = P (X_{1}) + P (X_{2}) + \dots + P (X_{k})

= \frac{1}{52} + \frac{1}{52}

\frac{1}{52} + \frac{1}{52} = \frac{1}{26}

= \frac{1}{26}
