From each section, we will get 1 queen. So, Total no. of chances of getting a queen from the deck of cards is 4.

Probability is calculated by No. of outcomes of that event / No. of possible outcomes. Then,

Finding the probability of getting queen:

⇒ P(Queen) = 4 / 52

⇒ P(Queen) = 1 / 13 or 0.0769230769...

Thus, the probability of getting a queen from the deck of cards is 1/13.

The cards are divided into different types like face cards, number cards and ace.

The face cards are King, Queen and Jack. Total no. of face cards is 3 × 4 = 12

The no. of number cards from 2-10 is 9 × 4 = 36. And the no. of aces (A) is 4.
