The sample space while rolling a die is
since there are 6 possible outcomes, the probability of obtaining any side of the die is
[tex]P(\text{one side)=}\frac{1}{6}[/tex]Then, the probability to have a number less than 3 is
[tex]P(\text{side 1)+P(side 2)=}\frac{1}{6}+\frac{1}{6}[/tex]since
[tex]\frac{1}{6}+\frac{1}{6}=\frac{2}{6}=\frac{1}{3}[/tex]we have
[tex]P(\text{side 1)+P(side 2)=}\frac{1}{3}[/tex]that is, the probability to get a number less than 3 is 1/3, which is equal to 0.333.
