Answer:
0.
Step-by-step 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.

Explanation:we will solve this question with help of linear programming.
Now, let Ben goes x times in buffalo trip and goes y times in Philadelphia trip. Thus, according to the question, Min Z= 180x+300y
And s.t.r. 2x+3y≤105, where x≥5, y≥15.
since at (0,0) 0≤105(true), so area of 2x+3y≤105 will cover the origin.
But, 0≥5 and 0≥15 are false, so their area will not cover the origin.
Thus, after drawing the graph of these three lines we will get a feasible reason of triangle ABC, where point A≡(5,31.667), B≡(5,15), and C≡(30,15)
Z at A- 180×5+300×31.667=10,400.1
at B-180×5+300×15=1350( which is minimum.)
at C- 180×30+300×15=5,850
Thus, Ben should go 5 times to buffalo trip and 15 times to Philadelphia to minimize his cost which is $1350.
