Question

One card is drawn from a well-shuffled deck of$52$cards. Find the probability of getting a king of red colour.

Answer 1

Finding the probability of getting a king of red colour:

In a pack of cards, there are total$52$cards, among which there are$13-13$cards of - “Heart”. “Spade”, “Diamond”, “Club".

Among these four types, heart and diamond are red-colored cards and spade and club are black-colored cards.

Among$13$cards, there are $\text{3}$ face cards (king, queen, and jack), one ace card & $9$ numbered cards.

Let's find the probability of getting a king of red colour.

Total number of cards,$\text{n(S)}$ =$52$

Number of king of red colour, $\text{n(E) = 2}$

$\text{P(getting red card) =}\frac{\text{no of favourable outcomes, n(E)}}{\text{total no of possible outcomes of event, n(S)}}$

$$\begin{gathered} =\frac{2}{52} \\ =\frac{1}{26} \end{gathered}$$

Hence, the probability of getting a king of red colour is$\frac{1}{26}.$
