## 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.
