What is the probability of getting green balls from the jar?
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 that all 3 balls drawn are different colors?
3/11
Three balls are drawn at random. The probability of being their different colours is. =3/11.
What is the probability of getting green?
Now, to find out the probability of getting a green ball we need the total number of favourable cases. We have 9 green balls in total. So the total number of favourable cases will be 9. So, the probability of getting a green ball is934 .
How many possible ways are there in drawing 3 balls from the box of 6 balls?
The bag contains 2 White, 3 Black and 4 Red balls. So, total 9 balls are there in the bag; among them 3 are Black and 6 are non-Black balls. Three balls can randomly be drawn in (9C3) = 84 ways. 1 Black and 2 non-Black balls can be drawn in (3C1)*(6C2) = 45 ways.
How many ways can 3 balls be selected?
Three balls can randomly be drawn in (9C3) = 84 ways. 1 Black and 2 non-Black balls can be drawn in (3C1)*(6C2) = 45 ways.
What is nCr formula?
The combinations formula is: nCr = n! / ((n – r)! r!) n = the number of items.
What is the probability of drawing a green white and non-red ball?
The probability of drawing a ball that is simultaneously “green, white and non-red” is zero, as there are no balls that are both green and white. Three balls are drawn one after the other from a bag containing 6 red balls, 5 yellow balls and 3 green balls.
How many red and green balls are in each bag?
Bag 1 contains 5 red and 3 green balls. Bag 2 contains 4 red and 6 green balls. Bag 2 contains 10 balls. 1. Probability of drawing a red ball from bag 1 and green ball from bag 2
What is the probability of two blue balls in a set?
If you started with differing numbers of balls of each color it would be more complicated and not too different from what you did. If we started with b blue, g green, and r red balls, the chance you get two blue balls is b ( b − 1) ( b + g + r) ( b + g + r − 1) with similar expressions for red and green.
What is the probability of getting all three oclours on first go?
The 1 3 is the probability of getting a certain colour on your first go. The 6 8 is the probability that the same colour is not picked on the second go. Finally, we multiply that by 3 so that we work out the probability for all three oclours.
