The probability is 0.
The probability is 1. It must be "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.
2 in 52 is the chance you would draw a black king in a deck of normal playing cards.
The probability, or probility, even, is 0 since tere can be no such thing as "choosing red card of the black".
Excluding jokers, the probability is 1 in 2.
Probability of drawing a black 7 from a standard 52-card deck is 2/52 or 1/26.
The probability of drawing a black card from a standard deck of 52 cards is 26 in 52, or 1 in 2, or 0.5.
It is 2/52 or 1/26.
The probability of drawing a black 8 from a standard deck of 52 card is 2 in 52 or 1 in 26 or about 0.03846.
The probability of picking a black ace in one random draw from a normal pack of playing cards is 1/26.
There are two black 7's and two red queen's in a standard deck of playing cards. The probability of drawing a black 7 is 2 in 52, or 1 in 26, or about 0.038. The probability of drawing a red queen from the remaining 51 cards is 2 in 51, or about 0.039. The probability, then, or drawing a black 7 followed by a red queen is (2 in 52) times (2 in 51), which is 4 in 2652, or 2 in 1326, or about 0.00151.
A laundry bag contains 160 black socks and 300 red socks. 1940 black socks must be added so that the probability of choosing a black sock is 7 of 8.
The Probability of Success = Number of successful outcomes/Number of outcomes.E.g. Find the probability of choosing a red five or a black odd numbered card in a standard deck of 52 playing cards.There are 2 red fives and 10 odd numbered cards, and a total of 52 cards, so:=2/52+10/52=12/523/13Probability of Red 5 or a Black Odd = 3/13* * * * *The above is true only for discrete distributions, not for continuous variables. For a continuous variable, with probability distribution function p(x), the probability that x lies between two values, a and b (ie a
2/52 or 1/26
The probability of drawing three black cards one at a time with replacement from a standard deck of 52 cards is 1/3x1/2x26/52, which is 0.833.
probability of hitting a white key 7/12, probability of hitting a black key 5/12. Assuming all key have an equal possibility of being hit.
There are 6 black face cards in a standard deck of 52 cards, so the probability of drawing a black face card in one try is 6/52 = 0.115
The probability of drawing one black seven from a standard deck of cards is 2/52 = 1/26. The probability of drawing the other black seven from the remaining 51 cards is 1/51. Therefore the probability of drawing both black sevens from a deck of cards = 1/26 x 1/51 = 1/1326 ~ 0.000754 (3sf).
Half the cards in a standard pack are black. Therefore the probability of drawing a black card is 1/2. Half the sides of a coin are "heads" so again the probability is 1/2. Therefore the probability you will both draw a black card and flip heads = 1/2 * 1/2 = 1/4.
It is 6/26 = 3/13
There are 52 cards of which 26 (a half) are black. So he probability that the first card is black is 26/52= 1/2
there is a 50% probability that you will pick a black card out of a full pack of playing cards
