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

Answer:

$\dfrac14$

Step-by-step explanation:

$\mathsf{Probability \ of \ an \ event \ occurring = \dfrac{Number \ of \ ways \ it \ can \ occur}{Total \ number \ of \ outcomes}}$

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:

$\dfrac{8}{32}$

Simplifying:

$\dfrac14$
