In a large population, 73% of the population are short-sighted. A samples of 7 people is randomly chosen from the population. Find the probability that
3 such samples of 7 people are taken.
(a) Find the probability that there are altogether 10 people who are short-sighted from the 3 samples.
A random sample of n people is chosen instead from the same population
(b) Find the minimum number n such that there is at least 99% chance of having one or more people who are short-sighted.

On a coordinate grid, point p is at (4, 3) and point r is at (−2, −5). points q and s are a reflection of both points across the x-axis. what are the coordinates of q and s? q(−4, 3), s(2, −5) q(4, −3), s(−2, 5) q(−4, −3), s(2, 5) q(−4, 3), s(−2, 5) ; -; i can't figure it out, if someone can me with the answer, that would be nice
