There is a .53846 probability (53.846%) if aces are counted as face cards. If they are not counted the probability drops to .48077 (48.077%)
P(7)= 1/30
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.
The answer depends on how many cards are picked and whether or not the cards are replaced before picking the next one. If only three cards are picked and they are not replaced, the probability is 3*2*1/(52*51*50) = 1/22100 = 0.000 045 2 If the cards are replace, the probability is 3*2*1/523 = 0.000 042 7
The probability of getting a king in a one card draw from a deck of 52 cards is .077 or 1 chance in 13. The probability of getting a king and one other specific denomination, such as a queen, is .154, or one chance in between 6 and 7.
