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 canβt 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 = 4β12 = 1β3

2. Probability of purple crayon

Possible outcomes : 12

Favorable outcome : 0

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

P = 0β12 =  0
