The probability is one half.
0.5
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).
26/52
It is 8/52 or 2/13
Probability of not drawing a black six from a deck of cards = 1 - probability of drawing a black 6 = 1 - 2/52 = 50/52 = 25/26.
1/26
The probability is one half.
0.5
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 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).
26/52
It is 8/52 or 2/13
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.
it is a 1/4
1/26
Excluding jokers, the probability is 1 in 2.
