The probability of drawing a jack is, P(J) = 1/13.The probability of drawing a queen is, P(Q) = 1/13.The probability of drawing a king is, P(K) = 1/13.The probability of drawing a jack or drawing a queen or drawing a king is;P(J or Q or K) = 1/13 + 1/13 + 1/13 = 3/13 = 0.23076923... ≈ 23.1%.
The probability of drawing a queen or king, in a single randomly drawn card, is 2/13. The probability of drawing one when you draw 45 cards without replacement is 1. The probability of choosing has nothing t do with the probability of drawing the card. I can choose a king but fail to find one!
It is 8/13.
There are 4 kings and 4 queens in a deck of 52 cards. The chance of drawing a king is 4 in 52 (or .077 in probability terms). The probability to draw either a king or a queen will be twice as high (.154)

The probability of drawing the queen of hearts is 1 in 52, or about 0.01923.

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 probability of drawing a Queen of Hearts from a standard deck is 1 in 52, or about 0.01923. The probability of drawing a blue card from a standard deck is zero, because there are no blue cards. Simply add them together 0.01923 + 0 = 0.01923.
The probability of drawing an Ace, King, and Queen from a standard deck of 52 cards, with replacement, is (4 in 52)3 or 64 in 140608, or 1 in 2197, or about 0.0004552.

There are 40 cards that are NOT jacks, queens, or kings, so the probability of drawing one of these cards is 40/52 = 10/13 = 0.769
