What is the probability that all are different Colours?

What is the probability that all are different Colours?

3/11
The probability of being their different colours is. =3/11.

What is the probability of picking 2 balls of the same color and different color when you have 1 white ball 2 red balls and 3 black balls in a bag?

Yes this is correct. P(2 balls are white) = P(first ball is white AND (second ball is white given first ball is white)) = P(first ball is white) * P(second ball is white | first ball is white) = 6/10 * 5/9, as you mentioned. In the same way, P(2 balls are red) = 4/10 * 3/9.

What is the probability that all 3 balls are different Colour?

The probability of the opposite event is 1–19/66=47/66.

What is the probability of getting a blue marble?

The probability of drawing a blue marble = 1/5.

What is the probability of getting a green ball?

If we randomly select a ball from the box: The chance of drawing a red ball is 2/6 = 1/3. The chance of drawing a green ball is 4/6 = 2/3.

What is the probability of obtaining a not yellow or blue marble?

The probability that the marble is not yellow is 0.8.

What is the probability of getting at least one red marble?

(The chance of getting at least one red marble, on the other hand, is 3/12 + 3/12 – (3/12 × 2/11), or only 10/22.)

What is the probability of getting both balls of the same color?

E = Event of getting both balls of the same color. therefore, 43. = 43 / 91. A bag contain 4 red balls, 6 yellow balls. If 3 balls are drawn randomly, then what is the probability that they are of the same color? therefore, 1 / 5. A bag contain 4 red balls, 6 yellow balls and 5 green balls.

How to calculate the probability of a ball being drawn?

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?

How many balls are in a bag of 3 Colours?

There are 12 balls in a bag. 3 of them are red, 4 of them are green, and 5 of them are blue. We randomly take out 3 balls from the bag at the same time. What is the probability that all three balls are of the same colour?

Are there different ways to choose 3 balls?

So, the way I think of it is: (1 red and 1 red and 1 red) or (1 green and 1 green and 1 green) or (1 blue and 1 blue and 1 blue). There are ( 5 3) + ( 4 3) + ( 3 3) total ways of having a success. There are a total of ( 12 3) different ways of choosing 3 balls.
