I have two black and two white cards, and you pick two cards at random from the four. What is
the probability that the two cards you get are of different colors?
P(Black card) = P(White card) = 2/4
P(2 cards are of different color) = P(first black and second white) + P(First white and second black)
= 2/4 * 2/3 + 2/4 * 2/3
= 0.6667

A jar contains black and white marbles. There are four more black marbles than white marbles. Two marbles are drawn from the jar at random. If the probability that the two marbles are the same color is equal to the probability that the two marbles are different colors, how many marbles are in the bag?
3. You have a standard deck of 52 playing cards. There are two colors (black and red) and four suits (spades are black, clubs are black, hearts are red, and diamonds are red). Each suit has 13 cards, in which there is an ace, numbered cards from 2 to 10, and three face cards (jack, queen, and king) a. You randomly draw and then replace a card. What's the probability it's an ace? What's the probability it's the 4 of...
We have two sealed boxes. In the first box we have 125 white and 75 black marbles. The second box contains 60 white and 90 black marbles. You pick a marble randomly from a box. For any given pick, the probability of picking from Box 1, P(B1) = 0.5. (a) What is the probability that the marble drawn is black? (b) The marble picked turns out to be black. What is the probability that it is picked out of Box...

If you pick five cards from a standard 52-deck, (a) what is the probability of getting two kings and three "4s"? (b) what is the probability of getting four ♣'s and one ♠? (c) what is the probability of getting three aces? (d) what is the probability of getting two ♢'s and two ♡'s?
b and c b) There are 20 socks in a drawer, 10 white and 10 black. Two socks are selected uniformly and at random. What is the probability both drawn socks are the same color? c) A standard card deck consists of 52 cards, made up of 13 cards of each of 4 different suits. Assuming the cards are selected with equal probability, what is the chance of a 5 card hand containing all cards of the same suit?
Problem(3)(20.) Suppose an urn contains 3 black balls and 4 white balls. Then, if you draw two balls without replacement, find the probability (a)both two balls are same colors. (b)two balls are different colors.
You have two decks of cards and draw a card from each at random. What is the probability of drawing a number smaller than 5 from the first deck and a jack from the second one?
