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.
