(xiii) Total number of $7$ of club is $1$ only.
As We know that, Probability = Number of favorable outcomes/ Total number of outcomes
Therefore, the probability of getting a $7$ of club $=1/52$
(xiv) Total number of jacks are $4$
As We know that, Probability = Number of favorable outcomes/ Total number of outcomes
Therefore, the probability of getting a jack $=4/52=1/13$
