Question 31 Probability Exercise 13.1

A card is drawn at random from a pack of 52 cards. Find the probability that the card drawn is black and a king.

Answer:

Solution:

The likelihood of an event happening is measured by probability. Many things are difficult to completely predict in advance. Using it, we can only forecast the probability, or likelihood, of an event occurring.

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 cards which are black and a king cards is 2

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

Thus, the probability of getting a black cards and a king is 2/52 = 1/26
