What is the probability of drawing a heart from a standard deck of cards?
What is the probability of drawing a heart from a standard deck of cards?
In a standard deck of 52 playing cards, the probability of drawing a heart is 13/52 = 1/4. A standard deck of 52 playing cards consists of 4 suits, therefore, a total of 52/4 = 13 kinds in each suit. 4 suits are clubs, spades, diamonds and hearts.
What is the probability of drawing a heart from a standard deck of cards on a second draw?

What is the probability of drawing a queen of hearts from a deck of 52 cards?
We pick a card, write down what it is, then put it back in the deck and draw again. To find the P(QQQ), we find the probability of drawing the first queen which is 4/52. The probability of drawing the second queen is also 4/52 and the third is 4/52.
What is the probability of pulling a heart?
The odds of drawing a King or a heart are P(E)/P(E’) = (4/13)/(9/13) = 4/9. What is the probability of getting at least one black card in a 7-card hand off a shuffled 52-card deck?
