Question

Lin has a die with 6 sides, each labeled 1, 2, 3, 4, 5, and 6. What is the probability that she will roll a 3? *

Answer 1

Probability of rolling number 3 =
`(1)/(6)`

Explanation:

Lin has a die with 6 sides.

Each side of the die is labeled with 1, 2, 3, 4, 5 and 6.

Since, probability of rolling any number =
`\frac{\text{Favorable event}}{\text{Total number of events}}`

Therefore, probability of rolling number 3 =
`\frac{\text{Favorable event}}{\text{Total number of events}}`

Favorable event of getting 3 in single roll = 1

Total events that can happen in one roll = 6

Therefore, probability of rolling number 3 =
`(1)/(6)`
