A bag contains 5 balls two balls are drawn at a random and found to be red what is the probability that all balls are red?
The probability that all balls are red is 0.50 or 50%.EXPLANATIONSuppose there are 4 boxes with 5 balls each.Box A has 2 red balls.Box B has 3 red balls.Box C has 4 red balls.Box D has 5 red balls.The probability of drawing at random 2 red balls for each box is:Box A; P(2 red balls) = (2/5)∙(1/4) = 2/20 = 1/10Box B; P(2 red balls) = (3/5)∙(2/4) = 6/20 = 3/10Box C; P(2 red balls) = (4/5)∙(3/4) = 12/20 = 6/10Box D; P(2 red balls) = (5/5)∙(4/4) = 20/20 = 10/10Now, suppose we do the drawing of 2 balls experiment 10 times on each boxgiving a total of 40 experiments. The probabilities calculated above are the"expected" results, that is; out of the 40 experiments (drawing of 2 balls), twored balls resulted:1 time came from box A3 times from box B6 times from box C10 times from box DNotice that from the 40 experiments, 20 result in 2 red balls.From here we have that when drawing 2 red balls the probability that it camefrom a box containing 2 red balls (box A), 3 red balls (box B), 4 red balls (box C)or 5 red balls is:P(A) = 1/20 = 0.05 = 5%P(B) = 3/20 = 0.15 = 15%P(C) = 6/20 = 0.30 = 30%P(D) = 10/20 = 0.50 = 50%
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.
A box contains 4 red balls and 2 black balls Three balls are drawn with replacement Let the random variable X be the number of red balls obtained?

Do the red balls means neutrons?
One cannot really answer this question without additional information. In what picture do red balls mean neutrons? It is true that in some pictures of an atomic nucleus the color red is used for neutrons, but this is a convention, it is semantics, neutrons themselves have no color (they don't even directly interact with light).
