Mutually exclusive and inclusive events only apply to probability.
Mutually exclusive events are two events that cannot happen at the same time. An example of this would be the probability of being male or female. You cannot be male-female, or female-male.
Mutually inclusive events are two events that can happen at the same time. An example of this would be the probability of drawing a red and the probability of drawing a jack in a deck of cards. It is possible to draw a red jack.
In that case, when you are calculating the probability of drawing a jack or a red, you must remember that there are two red jacks. This means that you cannot count the red jacks twice, so you must minus 2/52. Below is a link to a spreadsheet that Mr.Max created that may help you understand this concept better
