Question

Eight out of 32 students in the class wear

glasses. What is the probability that the first
student who walks out of the class will be
wearing glasses?

Answer 1

`\frac14`

Explanation:

`\mathsf{Probability \ of \ an \ event \ occurring = (Number \ of \ ways \ it \ can \ occur)/(Total \ number \ of \ outcomes)}`

If 8 students in a class of 32 wear glasses, then the probability of the first student who walks out of class wearing glasses will be:

`(8)/(32)`

Simplifying:

`\frac14`
