What is the probability of drawing a red checker from a bag of 9 black checkers and 6 red checker's replacing it and drawing another red checker?
There are 9+6 = 15 checkers in the bag. 6 of them are red. 6 out of 15 are red. Drawing a red checker has a probability of P = 6/15 = 2/5 = 0.4 = 40% Since you replace the checker, the probability Q that red is drawn again remains 0.4. The probability of both events occurring (red drawn twice) equals the product of probabilities, PQ = (0.4)*(0.4) = 0.16.
If you draw a card from a standard deck of cards what is the probability of drawing a red card or a face card?
The probability of drawing a red card is 1/2 (26/52).The probability of drawing a face card is 3/13 (12/52).The probability of drawing a red face card is 3/26 (6/52).The probability of drawing a red card or a face card is 8/13 (32/52).2 out of 52or 1 out of 26.
What is the probability for drawing a red or black card?
The probability of drawing a red or black card from a standard deck of playing cards is 1 (a certainty). This is because these are the only options available.
What is the probability of drawing a red card and a spade in two draws without replacing?
The probability of drawing a red card followed by a spade is (1 in 2) times (1 in 4), or 1 in 8, or 0.125. The probability of drawing a spade followed by a red card is (1 in 4) times (1 in 2), or 1 in 8, or 0.125. Since you have two distinct desired outcomes, add them together, giving a probability of drawing a red card and a spade of 0.25.
