3 out of 13 or 3/13
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
6 balls in a bag The probability of taking a red ball out of the bag is 0.5 A red ball is taken out of the bag and put to one side What is the probability of taking another red ball out of the bag?
0.4
What is the probability of picking a ball from a bag containing 4 red balls 3 green balls 2 yellow balls?
That depends. Picking a red ball is 4/9 Picking a green ball is 3/9 = 1/3 Picking a yellow ball is 2/9. Picking a ball is 9/9 or 1 because you'll always take one.
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
Karen has a bag of 4 blue balls 2 green balls 1 red ball What is the chance that she will pull a green ball from the bag?
2 in 7.
A bag contains 3 red balls and 4 green balls randomly draw one ball then replace it and randomly draw a second what is the percentage?
Drawing one red ball out of a bag that contains 3 red balls and 4 green balls is 3 in 7. If we are to randomly select one ball out of the bag and replace it (I assume with the same ball) then there are still 3 red balls and 4 green balls. The odds are still 3 in 7. It doesn't matter how many times you draw. Every time you draw a ball you have a 3 in 7 chance of pulling out a red ball.
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.
You are going to take a ball at random from a bag. The probability it will be red is two-fifths. There are eight red balls in the bag. How many of the balls are not red?
12
A bag contains 3 red balls and 2 blue balls a ball is taken at random from the bag and then put back what is the probability that both balls are red?
3c2+2c2+3c1 2c1 --------------- 7c2. I have done it this way. 3C2 means that the both balls would be green 2C2 both would be red and 3C1 and 2C1 because both the balls can be red and green.
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 does thrice as many red balls as green balls means?
Thrice means three times as many. If you have two green balls, it would mean you have six red balls.
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
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.
There are 2 red and 5 green balls in a bag If you randomly choose balls one at a time with replacement what is the probability of choosing 2 green balls and then 1 red ball?
Probability of first green: 5/7Probability of second green: 5/7Probability of a red: 2/7Probability of all 3 consecutive successes: (5/7) x (5/7) x (2/7) = 50/343 = 14.58% (rounded)
