Answer:
The complement of event A is:
Event A' = {rolling a 4, 5, or 6}
Step-by-step explanation:
The complement of an event A is all the posibles cases in which there is not an element of event A.
So, In this case we have 6 posibles elements: rolling a 1, 2, 3, 4, 5 or 6.
The complement of event A={rolling a 1, 2, or 3} is the event in which the number cube doesn't get 1, 2 or 3. That happens when it is rolling 4, 5 or 6 . Then, the complement of Event A that we are going to call A' is:
Event A'= {rolling a 4, 5, or 6}
