You draw 5 cards from a standard deck of 52 cards. If X is a random variable that represents the number of hearts you get, calculate the following: The probability of 3 or more hearts The expected number of hearts. Describe what this number means.
3. A hand of five cards is drawn simultaneously (without order or replacement) from a standard 52-card deck. Let A be the event that the hand includes four cards of the same kind, and let B be the event that at least two of the cards in the hand are of the same kind. a. Compute P(A) (5) b. Compute P(B). (5) c. Compute P(AB) (5) 4. Suppose Z and X are continuous random variables such that Z has a...
Assume that you are asked to select three cards without replacement from the 39 cards that contain the hearts, diamonds, and clubs from an ordinary deck of 52 playing cards. Let X be the number of clubs selected and Y the number of diamonds. (a) Find the joint probability distribution of X and Y. (b) Find P[(X,Y)EA), where A is the region given by {(x,y) | X + y2 2} (a) Complete the joint probability distribution below. (Type integers or...
Two cards are drawn without replacement from a standard deck of 52 52 playing cards. What is the probability of choosing a red card for the second card drawn, if the first card, drawn without replacement, was a spade? Express your answer as a fraction or a decimal number rounded to four decimal places.
Suppose we randomly select 5 cards without replacement from an ordinary deck of playing cards. What is the probability of getting exactly 2 red cards (fi.e, hearts or diamonds)? Select one: O C O a. 0.22640 b, 0.32513 e. 0.29235 d.0.44259 e.0.19277

Cards are dealt at random and without replacement from a standard 52-card deck. What is the probability that the third queen is dealt on the fifth card? (Round your answer to four decimal places.)
Problem 3: If 13 cards are to be chosen at random (without replacement) from an ordinary deck of 52 cards, find the probability that (a) 6 will be picture cards. (b) None will be picture cards.
