The probability of picking each colour out of the bag is calculated by dividing the number of blocks of that colour by the total number of blocks in the bag.
1. Red:
Number of red blocks = 10
Probability of picking a red block = 10/40 = 1/4 = 25%
2. Green:
Number of green blocks = 10
Probability of picking a green block = 10/40 = 1/4 = 25%
3. Purple:
Number of purple blocks = 10
Probability of picking a purple block = 10/40 = 1/4 = 25%
4. Yellow:
Number of yellow blocks = 10
Probability of picking a yellow block = 10/40 = 1/4 = 25%
Therefore, the probabilities of picking each colour out of the bag are:
- Red: 25%
- Green: 25%
- Purple: 25%
- Yellow: 25%
