If only two cards are drawn randomly from a standard deck, the probability is .00037, approx.
What is the probability of choosing king or jack?
If you select 45 cards without replacement from a regular deck of playing cards, the probability is 1. For a single randomly selected card, the probability is 2/13.
What is the probability of drawing two black kings from a standard deck of 52 cards?
The probability depends on:whether the cards are drawn randomly,how many cards are drawn, andwhether the cards are replaced before drawing the next card.If only 2 cards are drawn randomly, and without replacement, the probability is 0.00075 approximately.

What is the probability of drawing a red ten or a black ace?
The answer depends onwhether the card(s) are drawn from a normal deck of playing cards,whether they are at random,how many cards are drawn,whether the cards are replaced before drawing the next card.Thus, if 49 cards are drawn without replacement from an ordinary deck, whether randomly or not, the probability is 1.For a single card drawn randomly, the probability is 1/13.The answer depends onwhether the card(s) are drawn from a normal deck of playing cards,whether they are at random,how many cards are drawn,whether the cards are replaced before drawing the next card.Thus, if 49 cards are drawn without replacement from an ordinary deck, whether randomly or not, the probability is 1.For a single card drawn randomly, the probability is 1/13.The answer depends onwhether the card(s) are drawn from a normal deck of playing cards,whether they are at random,how many cards are drawn,whether the cards are replaced before drawing the next card.Thus, if 49 cards are drawn without replacement from an ordinary deck, whether randomly or not, the probability is 1.For a single card drawn randomly, the probability is 1/13.The answer depends onwhether the card(s) are drawn from a normal deck of playing cards,whether they are at random,how many cards are drawn,whether the cards are replaced before drawing the next card.Thus, if 49 cards are drawn without replacement from an ordinary deck, whether randomly or not, the probability is 1.For a single card drawn randomly, the probability is 1/13.

Non probability sampling is where the samples are not selected randomly.
What is the probability of choosing a queen or a king from a standard deck of cards?
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!
What is the probablity of drawing a red card or a queen?
If you draw more than 24 cards from a standard pack, without replacement, the probability is 1. That is, it is a certainty. The probability of the outcome for a single, randomly drawn card from a standard pack, is 7/13.
