two different cards are chosen at random from a standard deck of 52 cards find the probability that both cars are hearts given that both cards are the same color
probability that both cars are hearts given that both cards are the same color =P(both are hearts)/P(both are same color)
=(13/52)*(12/51)/(25/51)=3/25

We draw 5 cards randomly, and without replacement, from a standard 52-card deck. Find the probability that we get (a) three cards of one suit and two of another (b) at least three hearts
The following question involves a standard deck of 52 playing cards. In such a deck of cards there are four suits of 13 cards each. The four suits are: hearts, diamonds, clubs, and spades. The 26 cards included in hearts and diamonds are red. The 26 cards included in clubs and spades are black. The 13 cards in each suit are: 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King, and Ace. This means there are four...
1. We draw 5 cards randomly, and without replacement, from a standard 52-card deck. Find the probability that we get (a) three cards of one suit and two of another (b) at least three hearts
Draw 3 cards simultaneously from a standard deck of 52 playing cards. Then find: 1. Probably of observing all cards of the same face value 2. Probability of observing all cards of different face values 3. Probability of observing at least one king 4. Probability of observing exactly one diamond 5. Probability that two cards are kings and the other one is a diamond
5 cards are drawn at random from a standard deck. Find the probability that all the cards are hearts. Find the probability that all the cards are face cards. Note: Face cards are kings, queens, and jacks. Find the probability that all the cards are even. (Consider aces to be 1, jacks to be 11, queens to be 12, and kings to be 13)
An ordinary deck of playing cards has 52 cards. There are four suitslong dashspades, hearts, diamonds, and clubslong dashwith 13 cards in each suit. Spades and clubs are black; hearts and diamonds are red. One of these cards is selected at random. Let A denote the event that a red card is chosen. Find the probability that a red card is chosen, and express your answer in probability notation. The probability that a red card is chosen is _____=______
You are dealt two cards successively without replacement from a standard deck of 52 playing cards. Find the probability that both cards are black.
