I'm assuming you mean the coefficient matrix.

Answer:
Sample space= S= {1, 2, 3, 4, 5, 6}
One possible event is rolling an even number
probability (even number)
Step-by-step explanation:
Sample Space
The simple space is the combination of all possible outcomes
so,
Sample space= S= {1, 2, 3, 4, 5, 6}
One possible event
One possible event is rolling an even number
Probability of that event
to find the probability of the event i.e. rolling an even number, we first find the sample for the event i.e. event space
event space={2, 4, 6}
Now,
probability (even number)
