Once you have picked the first ball, you will have five left to pick from, one of which will be the same color as the first pick, and four of colors that you don't want. The probability of picking the second ball of the same color is then 1/5 or 0.20. P.S. It really isn't fair to have someone else do your homework for you.

A bag has 8 blacks balls and 2 white balls what is the probability of picking one black ball without looking Write your answer as a decimal whats the answer?
0.8.
When jar contains 6 blue balls 8 red balls and 6 yellow balls 2 balls selected without replacement.what is probability that first ball is red and second ball is blue?
If the balls are selected at random, then the probability is 12/95.
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.
A box contains 7 red balls and 11 black balls two balls are taken out one after the other without replacement what is the probability that both balls are black?
11/18 x 10/17 = .359

What are the three ways that probability can be expressed?
Probability can be expressed as a ratio, a fraction, or a decimal. For example if there are 4 red balls and 4 white balls in a bucket and you pick one without looking the probability (chance) that you will pick a red ball is a half, because half the balls are that colour. You can say that the probability of that happening is 1/2 or 50% or 0.5 The probability is the same for choosing a white ball. * * * * * There is a fourth way, and that is in the form of odds.
If there are 6 green balls 3 red balls and 1 pink ball in a container what is the probability of choosing a green ball without looking in the container first?
6/10 or reduced is 3/5
When jar contains 6 blue balls 8 red balls and 6 yellow balls 2 balls selected without replacement.what is probability that first ball is red and second ball is blue?
If the balls are selected at random, then the probability is 12/95.
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 getting 3 red balls from an urn in 3 picks without replacement if the urn contains 5 red 3 blue?
The probability the first ball will be red is 5/8. The probability that the first and second balls will be red is 5/8 x 4/7. The probability that the first, second, and third balls will be red is 5/8 x 4/7 x 3/6, or overall 60/336 (about 17.86%).
If you draw 5 balls with replacement from an urn containing white balls and black balls is the probability of getting 3 white balls always higher than if you draw the balls without replacement?
The probability of getting 3 white balls in a draw of 5 balls with replacement from an urn containing white balls and black balls is always greater than the same test without replacement, because the number of white balls decreases when you draw a white ball and do not replace it. The ratio of white to black with replacement is constant, and is always less than one, assuming there is at least one black ball. The ratio of white to black without replacement decreases each turn, and is still less than one, and is less than the previous ratio, unless the question asked about 2 white balls or less.
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 getting a red balls from an urn containing 2 red 3 green and 2 white balls?
2/7 = 28.57%
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.
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 box contains 7 red balls and 11 black balls two balls are taken out one after the other without replacement what is the probability that both balls are black?
11/18 x 10/17 = .359
