Answer:
0.
Explanation:
It is given that a dartboard has 20 equally divided wedges, and we are awarded the number of points in the section your dart lands in.
It means you can score from 1 to 20 in one trial.
We need to find the probability we will score 21 points.
Number of wedges with mark 21 = 0
Total number of wedges = 20
Therefore, the required probability is 0. It means it is an impossible event.
