Answer 1

In logic and probability theory, two propositions (or events) are mutually exclusive or disjoint if they cannot both be true (occur). A clear example is the set of outcomes of a single coin toss, which can result in either heads or tails, but not both.

Answer 2

Look if i roll 4 can it increase or decrease the possibilty of an occurence of 3?

Answer 3

you only rolled it once. you cannot get a three and a four at the same time. so they are mutually exclusive
