Answer: Rolling a 4 or rolling an odd number are examples of mutually exclusive events.
Mutually exclusive events are events that cannot happen at the same time. You cannot roll one die and get both a 4 and an odd number. They are completely different.
However, in choice 1, you can roll a 3 and a number greater than 1. If you rolled the number 3 itself, it is both a 3 and greater than 1.
