Step-by-step explanation:

Angle subtended by the diameter
The theorem to solve this is:
The angle subtended by an arc is twice the angle it subtends.

You can think of this experiment as follows: you have to select a random number between 1 and 15, where each number is equally likely to appear.
Player A wins if 3,4,5 or 6 are picked.
Player B wind is 10,11 or 12 are picked.
Two events are said to be mutually exclusive if they cannot happen at the same time. So, in our metaphor, the question is: can we pick a particular number, so that both players win simultaneously?
The question is no, because if player A wins, we have picked 3,4,5 or 6, and player B wins with none of these numbers.
Similarly, if player B wins, we have picked 10, 11 or 12, and player A wins with none of these numbers.
So, the two events cannot occur simultaneously.
If you want to be more formal, since the events are subset of the sample space, two events are mutually exclusive if their intersection is the empty set, and this is the case:
