Concept: The question tests on Probability
Solution:
12 picture cards has 4 Kings, 4 Queens and 4 Jacks in it.
If he is holding 1 king, the probability of getting the 1st King is 1.
We now have the remaining 11 cards in which there are 3 Kings.
Probability = Favorable Outcomes / Total Outcomes = 3C1/11C1=3/11
If he is holding a spade, we are not sure if it is a king.
Probability = Favorable Outcomes / Total Outcomes = 4C2/12C2=1/11
The required probability = 3/11 + 1/11 = 4/11
