A dice is rolled once. What is the probability that the number on top will be a factor of 6 ?
A dice is rolled once, the possible outcomes are 1, 2, 3, 4, 5 and 6.
Then,
The probability that the number on top will be a factor of 6
Factors of 6 are 1, 2, 3 and 6
Probability = total number of factor of 6/ Total number of outcomes
= 4/6 … [divide numerator and denominator by 2]
= 2/3
