Chance of a dice landing on '1'
- There is only one number '1' on a dice.
- So the number of ways the result can happen = 1.
- There are 6 sides on a dice.
- So the number of possible results = 6.

Probability - dice landing on '1'
- This means the chance of rolling a dice and landing on '1' is 1⁄6.
