A box contains 75 balls numbered from 1 to 75. If 12 balls are drawn with replacement what is the probability that at least two of them have the same number?
It is 0.6050
A bag contains 7 red 10 blue and 3 yellow balls If a ball is drawn at random what is the probability that a blue ball is drawn?
20 marbles total, 10 of which are blue so, odds of drawing blue are 10/20=.5=50%
One ball is drawn at random from a bag containing 17 red balls and 4 white balls what is the probability that the ball is red?
17 out of 21
A jar contains 11 white and 21 blue marbles a marble is drawn at random pnot blue express the probability as a fraction?
Probability of not blue is the probability of white. The probability of white is 11/(11+21) or 11/32.
An Urn contains 5 white and 7 black balls five balls drawn at randoma Find the distribution function of the probability distribution of no of white balls?
with replacement: binominal distribution f(k;n,p) = f(0;5,5/12) without replacement: hypergeometric distribution f(k;N,m,n) = f(0;12,5,5)

It is 0.6050
If A box contains three black balls and four gold balls Two balls are randomly drawn in succession from the box If there is no replacement what is the probability that both balls are black?
(3/7)*(2/7)=(6/49) You have a 6 out of 49 probability.
If an urn contains 6 yellow balls 3 red balls and 5 blue balls If 2 balls are drawn without replacement what is the probability of drawing 2 yellow balls?
The probability is (6/14)*(5/13) = 30/182 = 0.1648 approx.
What is the probability of choosing 3 red balls and 2 black balls out of a bag which contains 5 red balls 2 green balls and 4 black balls?
If you draw enough balls, without replacement, the probability is 1.The answer depends onhow many balls are drawn, andwhether or not they are replaced.Unfortunately, your question gives no information on these matters.
A bucket contains 50 lottery balls numbered 1-50. One is drawn at random. What is the probability of the number being 2- digit number?
40/50
A bag containing 4 green 6 black 7 white balls a ball is drawn at randomly probability of finding 2 red balls?
The probability is zero, because there are no red balls in the bag.
A bag contains 7 red 10 blue and 3 yellow balls If a ball is drawn at random what is the probability that a blue ball is drawn?
20 marbles total, 10 of which are blue so, odds of drawing blue are 10/20=.5=50%
One ball is drawn at random from a bag containing 17 red balls and 4 white balls what is the probability that the ball is red?
17 out of 21
Box a contains 5 blue balls and 4 white balls. box b has 2 blue and 5 white balls. one ball is drawn at random from box a and transferred to box b without looking. what is the probability of drawing a?
The question cannot be answered because it is incomplete and a complete version cannot be found.
A bag contains 7 red 5 blue 4 white and 4 black balls find the probability that a ball drawn at random is red or white?
It is (7+4)/(7+5+4+4) = 11/20
A jar contains 11 white and 21 blue marbles a marble is drawn at random pnot blue express the probability as a fraction?
Probability of not blue is the probability of white. The probability of white is 11/(11+21) or 11/32.

with replacement: binominal distribution f(k;n,p) = f(0;5,5/12) without replacement: hypergeometric distribution f(k;N,m,n) = f(0;12,5,5)
