Basic Concepts of Probability · Example 1

Consider an experiment that consists of rolling a single standard 6-sided die (with faces numbered 1-6). Decide if these probabilities are equal to zero, equal to one, or somewhere in between.

(a) $P\left(\text{roll a 4}\right)$
(b) $P\left(\text{roll a 7}\right)$
(c) $P\left(\text{roll a positive number}\right)$
(d) $P\left(\text{roll a}\frac{1}{3}\right)$
(e) $P\left(\text{roll an even number}\right)$
(f) $P\left(\text{roll a single}-\text{digit number}\right)$
