Question

If a single card is drawn from an ordinary deck of cards, what is the probability of drawing a jack, queen, king, or ace?

Answer 1

`P("randomly draw a Jack, Queen, King, or Ace")=16/52=4/13`

Explanation:

A standard deck has 13 ordinal cards (Ace, 2-10, Jack, Queen, King) with one of each in each of four suits (Hearts, Diamonds, Spades, Clubs), for a total of `13xx4=52` cards.

If we draw a card from a standard deck, there are 52 cards we might get.

There are 16 cards that will satisfy the condition of picking a Jack, Queen, King, or Ace.

This gives us:

`P("randomly draw a Jack, Queen, King, or Ace")=16/52=4/13`
