what is the probability of rolling less than 3 on a single roll of a six-sided die?

Question

options: 

1/3 or 1/2

Answer 1

The probability of rolling less than a three is the probability of rolling a one or a two. The probability of rolling any given number is 1/6 since there are six sides. Therefore, the probability will be P(1)+P(2)=(1/6)+(1/6)=2/6=1/3.
