Solution:

The mathematical term describing the possibility that something will happen is "probability. It is the capacity to comprehend and measure the likelihood of various combinations of outcomes.

Given: A card is drawn at random from a pack of 52 cards

Required to Find: Probability of the following

Total number of cards in a pack = 52

Total number of black cards is (13 + 13) 26

Total number of kings are 4 in which 2 black kings are also included.

So, the total number of black cards or king will be 26+2 = 28

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

Thus, the probability of getting a black cards or a king = 28/52 = 7/13
