Respuesta :
there are 52 cards in a standard deck. 4 of these are queens. therefore there is a 4/52 or 1/13 chance of drawing a queen at random
if you draw a card at random and ate told it is a face card (J, Q, or K) then there are 4 queens out of 12 face cards = 4/12or 1/3 chance you drew a queen
please ask for more help or clarification

Probabilities are used to determine the chances of an event.
- The probability of selecting a queen in a standard deck is 1/13
- The probability of selecting a queen from Jack, Queen or King is 1/3
(a) Probability of selecting a queen from a standard-deck
In a standard-deck, we have:
[tex]\mathbf{Cards= 52}[/tex]
[tex]\mathbf{Queen= 4}[/tex]
So, the probability of selecting a queen is;
[tex]\mathbf{P(Queen) = \frac{Queen}{Cards}}[/tex]
[tex]\mathbf{P(Queen) = \frac{4}{52}}[/tex]
Simplify
[tex]\mathbf{P(Queen) = \frac{1}{13}}[/tex]
Hence, the probability of selecting a queen in a standard deck is 1/13
(b) Probability of selecting a queen from (Jack, Queen, King)
We have:
[tex]\mathbf{Cards= 3}[/tex]
[tex]\mathbf{Queen= 1}[/tex]
So, the probability of selecting a queen is;
[tex]\mathbf{P(Queen) = \frac{Queen}{Cards}}[/tex]
[tex]\mathbf{P(Queen) = \frac{1}{3}}[/tex]
Hence, the probability of selecting a queen from Jack, Queen or King is 1/3
