You can draw any one of 80 different marbles.
Any one of 50 draws will be successful.
Probability of success = 50/80 = 0.625 = 62.5 %

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 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 probability of drawing a black 5 or a king of clubs from a standard deck of cards?
It is 5/52 for a single card, drawn randomly.
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.

You are given a deck of cards if you randomly pick one card what is the probability of drawing aspade reduce answer to lowest terms?
13/52, or 1/4.
What is the probability of drawing a card from each of 4 decks and getting the nine of clubs from all decks?
the probablility of drawing a nine or clubs from all four randomly shuffled decks with 52 cards is 1 out of 7,311,616
A bag contains 6 red marbles 7 blue marbles and 6 green marbles If one marble is randomly picked from the bag what is the probability that this is a blue marble?
There would be a 7/19 or 36.84% chance of drawing a blue marble from the bag.
What is the probability of drawing a heart or club from a pack of cards?
Probability of drawing a heart: 1/4 Probability of drawing a club: 1/4 Probability of drawing a heart or a club: 1/4 + 1/4 = 2/4 = 1/2
If a box contains 4 red marbles seven white and 5 blue and two marbles are drawn one at a time with replacement What is the probability that both marbles are white?
Since the box contains 16 marbles, seven of them white, then the probability of drawing one white marble is 7/16. If you replace the marble and draw again, the probability of drawing another white marble is still 7/16. The net probability of drawing two white marbles, while replacing the first, is 49/256.
What is the probability of drawing a club and a 9 from a deck of 52 playing cards?
The answer depends on whether or not the card is drawn randomly and also, whether or not the card drawn in the first attempt is replace.
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.
