Question

A single die is rolled one time. Find the probability of rolling an odd number or a number less than 3.

Answer 1

The probability of rolling an odd number is 3/6
The probability of folling a number less than three is 2/6
The probability of one roll giving either of the results is:
\[P=\frac{3}{6}+\frac{2}{6}=\frac{5}{6}\]
