The event by definition that covers the entire sample space of the experiment is;
<em><u>The number is even or less than 12</u></em>
We are given the numbers in the set as;
set {2, 3, 4,... 10}.
Now, the numbers in the set are even and odd numbers from 2 to 10 with 10 being the highest and 2 being the lowest.
Thus the event that covers this sample space is simply a set of numbers that are even or less than 12.
