Facts, right?

Right.

Definition: When A and B have no outcomes in common, they are said to be mutually exclusive.
(Probability and Statistics for Engineering and the Sciences, Fourth Edition, Jay L. Devore, PG 47)

Diagram:

In more understandable terms: if something is in the A circle, then it cannot also be in the B circle. For example, if you have one hour and you choose to play basketball for that hour, then you cannot play football for that same hour. In that hour of time basketball and football are mutually exclusive.

The same is true for the time that we have to watch television. There are certain choices we make and unfortunately we cannot do two different activities with the same hour. We cannot watch television and play basketball in the same hour. We are forced into a choice. And the choice is between two activities which are mutually exclusive, TV and basketball. So if we were to choose to spend our 2 hours and 46 minutes per day watching television, what other activities would we be giving up, simply because they are mutually exclusive.

In almost all cases, the activities in B cannot be achieved at the same time as the activity in A.

Fact: The average youth spends 19 hours and 11 minutes every week watching television.

Fact: The principle of Mutually Exclusive activities is true. (the proof will be left out for the good of every sane human)

So is this right or wrong?

And what are those kids watching, anyhow?
