What is the probability of selecting a red ball?

The probability of picking a ball from a bag is the number of balls of that colour divided by the total number of balls. Therefore in the first instance, the probability of a red ball is 3/9 or 1/3rd. If that ball is now removed the probability of picking a 2nd is 2/8 or 1/4.

What is the probability that a red ball is taken?

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.

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.

What is the probability that at least one red ball is not?

The probability that at least one red = Probability of first one red and second is not red + Probability of first one red and second balls is red+Probability of first ball is not red and second ball is red. A bag contains 5 white and 3 red balls. One ball is drawn at random.

How many white balls are in a bag of random balls?

A bag contains 8 white balls and 6 black balls. If we taken out two random balls from that bag, then find the probability that they are of the same color? Here S be the sample space. therefore, 91.

What is the probability of drawing two red balls in blackjack?

The probability of getting a second red is 7 (red balls remains) / 13 (balls remaining). Assuming that the results of the first and second draws are independent,the probability of drawing two red balls is therefore (4/7)* (7/13) = 4/13. Now, suppose instead of a red on the first draw you got white.
