What is the probability that you will pick a red 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 that he will pick a yellow ball?
1/3
What is the probability of picking a yellow? The probability is the number of yellows in the bag divided by the total number of balls, i.e. 2/6 = 1/3. There is a bag full of coloured balls, red, blue, green and orange.

| Outcome | An outcome of a probability experiment is one possible end result. |
| Total Outcomes | In probability, the total outcomes are the total number of possible outcomes for the probability experiment. |
What is the value of 5c 2?
5 CHOOSE 2 = 10 possible combinations. 10 is the total number of all possible combinations for choosing 2 elements at a time from 5 distinct elements without considering the order of elements in statistics & probability surveys or experiments.
What is N and R in nPr?
Permutation: nPr represents the probability of selecting an ordered set of ‘r’ objects from a group of ‘n’ number of objects. The order of objects matters in case of permutation. The formula to find nPr is given by: Where n is the total number of objects and r is the number of selected objects.
How many red balls and blue balls are there together?
Assuming 3 blue balls are not together, we have to maintain a gap between ‘y’ and ‘b’ or between ‘b’ and ‘y’ , by placing at least 1 red ball ‘r’ There are 6 identical red balls and 3 identical blue balls. In how many ways can you arrange them such that exactly 2 of the 3 blue balls are together?
What is the total number of arrangements that no two balls?
Hence total number of arrangements such that no two balls of the same colour are next to each other = 5C3 = 10. A box contains 4 red balls, 3 blue balls and 5 yellow balls. In how many ways will 5 balls be selected so as there will be exactly 3 red balls? There are 12 balls in the box of which 4 are red, 3 are blue and 5 are yellow.
What is the probability that the red balls are red?
For the red balls, it is 2 6 and for the yellow balls 3 6 or half a chance. Two balls are drawn from a bag containing 3 red, 3 green and 4 black balls. What is the probability that both are red?
What is the probability that the second ball will be blue?
If the first ball was blue, there will be 1 blue and 2 red balls in the bag when we pick the second ball. So the probability of getting a blue is 1/3. However, if the first ball was red, there will be 1 red and 2 blue balls left so the probability the second ball is blue is 2/3.
