Question:
At the archery training ground, some archers shoot arrows at targets at a distance of between 20 meter and 70 meter. The probability of hitting a target with one shot is p. When shooting from a distance d meter, p = 0.015 (70 - d). Each arrow is released independently.
1. Can you explain why this is a binomial probability distribution case, assuming y shots are taken?
2. An archer releases 10 arrows from a distance of 40 meter.
A. Find the probability that exactly 4 arrows hit the target!
B. Find the probability that at least 8 arrows hit the target!
3. Another archer releases 20 arrows from a distance of x meter, find the value of x if the Archer has an 80% chance of hitting the target at least once!
