Answer
Fraction of outcomes less than 5 = $\frac{2}{3}$
Work Step by Step
When a die rolled then the total outcomes = (1, 2, 3, 4, 5, 6) = 6
If outcomes less than 5 then the favorable outcomes = (1, 2, 3, 4) = 4
Probability = $\frac{Favorable outcomes}{total outcomes}$
Probability of being less than 5 = $\frac{4}{6}$
= $\frac{2}{3}$
Fraction of outcomes less than 5 = $\frac{2}{3}$
