What is the probability that the ball is either green or red?
There are 12 possible balls you can draw so the denominator will be 12, there are 4 red balls and 3 green balls, so there are 7 balls that fit the requirement of being either red or green. The probability of drawing either a red or a green ball is 7/12.
What is the probability of drawing a white ball from a bag containing 3 black balls and 4 white balls?
Two balls are drawn one by one at random without replacement. The probability that the second drawn ball is white. Therefore, the probability that the second drawn ball is white = (2/7) + (2/7) = 4/7.
What is the probability that the first ball is red and the second ball is blue?
two out of 49
Eight forty-ninths multiplied by twelve forty-eighths is equal to two forty-ninths. Therefore, the probability that the first ball is red and the second ball is blue is two out of 49 — two forty-ninths.
What is the probability that the first ball is red and the second is black?
15 out of 36
There are now 21 red balls, and there are still 15 black balls. This is a total of 36, and the probability of selecting a black ball now is 15 out of 36. This is the probability we are looking for. The probability that the second ball is black given that the first ball is red is 15 out of 36.
What is the probability of drawing a white ball from a bag containing 3?
So, probability will be 3/7.
What is the probability of drawing 3 white balls?
The sample space for drawing 3 balls is {WWW,BBB,RRR,WBB,WRR,RBB,RWW,BRR,BWW}. So required probability is 1/9. But answer given is 1/56.
What is the probability that the ball is red?
Therefore the probability of getting a red ball is 9/20. Therefore the probability of getting a white ball is 7/20. Therefore the probability of getting a black ball is 1/5. Therefore the probability of getting not a black ball is 4/5.
What is the probability that the balls drawn contain different colors?
A bag contain 2 red balls, 6 yellow balls and 4 green balls. If 3 balls are drawn randomly, then what is the probability that the balls drawn contain balls of different colors? = 48. = 12 / 55. A bag contain 2 red balls, 6 yellow balls and 4 green balls.
How many green and red balls are there in each bag?
A bag A contains 4 green and 6 red balls. Another bag B contains 3 green and 4 red balls. If one ball is drawn from each bag, find the probability that both are green.
What are the chances of catching a ball from the bag?
When you catch a ball from the bag you have two chances: red (in 4/7 of the cases) and green (in 3/7 of the cases). When you put it the again in the bag you have same initial situation, so events are independent.
How many balls can be selected from remaining 12 4?
Rest 1 ball can be selected from remaining ( 12 – 4 ) = 8 balls in 8 C 1. = 42 / 55. A bag contain 2 red balls, 6 yellow balls and 4 green balls. If 3 balls are drawn randomly, then what is the probability that the balls drawn contain no yellow ball?
