Question

one card is drawn at random from a pack of 52 cards. what is the probability that it is a king or queen​

Answer 1

Answer:

I’m not 100% sure what you mean in this question, but I can answer both of my interpretations.

 

There are 13 values for cards: ace, 2–10, Jack, Queen and King. You want 2 out of the 13 possibilities, so the chance is 2/13.

What is the probility of picking a queen and a king on my two first picks?

First pick: Either a king or queen is fine, so the probability is 2/13, like we proved before.

Second pick: Now we are just trying to pick the other wanted value, queen if we got a king and king if we got a queen. There are 4 of each card value and there are 52–1 cards left, (we already took a card out) so the probability of getting the other wanted value is 4/51.

We just have to multiply these two fractions together to get the probability of all of this to happen in a row: 2/13 x 4/51 = 8/663.

Step-by-step explanation:

Answer 2

The probability that it is a king or queen​ is $\dfrac{2}{13}$.

Step-by-step explanation:

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

To find : What is the probability that it is a king or queen​ ?

Solution :

Total numbers of cards are 52.

Favorable outcome of number of a king or queen = 4+4=8

The probability that it is a king or queen​ is given by,

$\text{Probability}=\frac{\text{Favorable outcome}}{\text{Total outcome}}$

$\text{Probability}=\frac{8}{52}$

$\text{Probability}=\frac{2}{13}$
