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 = 4β12 = 1β3
2. Probability of purple crayon
Possible outcomes : 12
Favorable outcome : 0
Probability (P) = Number of favourable outcomes/Total Number of outcomes
P = 0β12 = 0
