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.
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.
What is the probability of pulling of pulling out a blue marble returning it to the jar and then pulling out a green marble?
The probability is B*G/(B+G+R)^2where B = number of Blue marbles G = number of Green marbles and R = number of marbles of other colours.
What is the probability of drawing a white ball out of a bag with 2 green 3 white and 5 black?
The probability of a simple event is the number of ways to succeed over the total possibilities. So, there are three white balls, and ten balls total. So: P(white) = 3/10
What is the probability of having 2 red balls when chosen in random from a container has 2 red balls 4 green balls and 2 yellow balls?
1/4 chance

When an urn contains 12 red balls 153 blue balls 2 black balls 47 white balls and no green balls What is the probability you do not draw any ball at all?

A bag contain 4 green 6 black 7 white balls a ball is drawn at random what is the probability that it is a green or a black ball?
This is a law of addition probability which states that the probability of A or B equals the probability of A plus the probability of B minus the probability of A and B. Written in mathematical terms, the equation is: P(AorB) = P(A) + P(B) - P(AnB) where P(AnB) = 0 (since you can not pull out a green and black ball at the same time). Let P(A) = Probability of drawing the green ball & let P(B) = Probability of drawing the black ball. Total outcomes is 17. So, P(A) = 4/17 & P(B) = 6/17. Therefore P(green or black) = 4/17 + 6/17 = 10/17.
In a bag of 6 red marbles 14 green marbles what is the probability of pulling out a red or green?

What is the probability of pulling of pulling out a blue marble returning it to the jar and then pulling out a green marble?
The probability is B*G/(B+G+R)^2where B = number of Blue marbles G = number of Green marbles and R = number of marbles of other colours.
If you have 4 green balls 2 red balls and 1 blue what is probability of getting a green?
It is 1/7 if a ball is selected at random.
What is the probability of drawing a white ball out of a bag with 2 green 3 white and 5 black?
The probability of a simple event is the number of ways to succeed over the total possibilities. So, there are three white balls, and ten balls total. So: P(white) = 3/10

1/4 chance
What is the probability of picking a red ball out of a bag containing 3 red balls 4 blue balls and 6 green balls?
3 out of 13 or 3/13
What is the probability of getting a red balls from an urn containing 2 red 3 green and 2 white balls?
2/7 = 28.57%
If there are 4 balls in a bag one is blue and the rest are red what is the probability to pull out a green ball?
zero
