Probability : Colourful Crayons

Learning probability can be made enjoyable by incorporating interactive games and activities.

Children love doing this activity and this concept is practised in a better way by doing this activity.

** Materials required for the activity **: Take crayons of different colours like red (3), yellow (2), blue (4), pink (3), a paper bag, a sheet of paper, and a pen.

- All crayons should be of the same size so that canβt be distinguished by touching.
- Firstly, gather all the crayons and place them in the paper bag.
- Then, instruct the children to take out a specific crayon from the bag without peeking.
- Afterward, proceed to ask the children simple questions regarding the probability of certain outcomes.
- For instance, ask them to determine the probability of :
- Drawing the blue crayon from the bag
- Picking the purple crayon from the bag.

## Answers :

1. **Probability of blue crayon **

Possible outcomes : 12

Favorable outcome : 4

Probability (P) = Number of favourable outcomes/Total Number of outcomes

P = ^{4}β_{12} = ^{1}β_{3}

2. **Probability of purple crayon **

Possible outcomes : 12

Favorable outcome : 0

Probability (P) = Number of favourable outcomes/Total Number of outcomes

P = ^{0}β_{12} = 0
