Cedric has 4 pencils and blue pens and a black pen in his desk if he randomly draws two of them from the desk without replacement what is the probability he will draw the two pen?

This question has some missing information but the way you do this problem is to multiply fractions formed by probabilities.
To draw two pens out of the drawer first take the ratio (fraction) of the number of pens over the total number of writing tools. Then, multiply that by one less on the top and the bottom.
Lets say you have 4 pencils, 2 blues and 1 black. Seven total.
2/7*1/6=2/42 probability.

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 probability without replacement?
completely useless.
In a bag there are 3 red marbles and B blue marbles. Two marbles are randomly selected from the bag without replacement. The probability that the two marbles are the same color is 0.5. What is the sum?

What is it called when you pick an object and do not return it in probability?
When you pick an object and do not return it, in probability it is termed "without replacement".

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.

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.
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 two aces from a deck of 52 cards?
The answer depends on how many cards are drawn, and whether they are drawn with or without replacement. If 1 card is drawn, the probability is 0, if 50 cards are drawn (without replacement), the probability is 1. If only two cards are drawn, at random and without replacement, the probability is (4/52)*(3/51) = 12/2652 = 0.0045
If 5 cards are drawn from a deck of cards without replacement What is the Probability that at least One of the cards is a 3?
If five cards are drawn from a deck of cards without replacement, what is the probability that at least one of the cards is a heart?
If two cards are randomly drawn from a standard deck without replacement what is the probability of getting a pair?
hypergeometric distribution f(k;N,n,m) = f(1;51,3,1) or binominal distribution f(k;n,p) = f(1;1,3/51) would result in same probability
