If A card is drawn at random from a pack of $52$ cards then Find the probability that the card drawn is:(iii) black and a king (iv) a jack, queen or a king

(iii) Total number of cards which are black and a king card is $2$

As We know that, Probability = Number of favorable outcomes/ Total number of outcomes

Therefore, the probability of getting a black card and a king is $2/52=1/26$

(iv) A jack, queen or a king are $3$ from each $4$ suits.

Thus, the total number of a jack, queen and king are $12$.

As We know that, Probability = Number of favorable outcomes/ Total number of outcomes

Therefore, the probability of getting a jack, queen or a king is $12/52=3/13$
