What is the probability of two balls being same Colour?

The probability that both balls are the same color is 0.44.

What is the probability that both balls will be red?

In conclusion, the probability that both of the balls are red is 1/10.

What is the probability of picking up 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 of picking one blue ball in probability?

In the second bag, to calculate the probability of pick 1 blue ball , we follow the same rationale explain above: the sample space contain 16 balls ( 2 blue and 14 red balls), then the probability to pick 1 ball blue is to divide the number de blue balls (2) by total number of balls (16) = 2/16 = 0.125.

How do you find the probability of two balls of the same?

With conditional probability, you could formulate it this way: P (2 balls of the same color) = P (2 balls are white OR 2 balls are red) = P (2 balls are white) + P (2 balls are red) [since the two conditions are mutually exclusive]

What are the odds of randomly picking two different colors?

There is 1 way to choose 2 red and 3 ways to choose 2 black, so 4/15 chance of picking two of the same color and the other 11/15 have to be ways to pick two of a different color (5 ways to pair a white with a black or red and 6 to pair a red with one of the blacks). Ways to randomly pick 2 balls from among 6 randomly distributed balls = 6!/4! = 30.

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?
