Answer:The general equation of a sphere is: (x - a)² + (y - b)² + (z - c)² = r², where (a, b, c) represents the center of the sphere, r represents the radius, and x, y, and z are the coordinates of the points on the surface of the sphere.

Step-by-step explanation:
Given that a university found that 20% of its students withdraw without completing the introductory statistics course.
Each student is independent of the other and there are only two outcomes
X no of students in the registered 20 is binomial with p = 0.2
a)the probability that two or fewer will withdraw.
=![P(X\leq 2)\\=0.2061](https://tex.z-dn.net/?f=P%28X%5Cleq%202%29%5C%5C%3D0.2061)
b. Compute the probability that exactly four will withdraw.
=![P(X=4) = 0.2182](https://tex.z-dn.net/?f=P%28X%3D4%29%20%3D%200.2182)
c. Compute the probability that more than three will withdraw.
![=P(X>3)\\\\=1-F(2)\\= 1-0.4115\\=0.5885](https://tex.z-dn.net/?f=%3DP%28X%3E3%29%5C%5C%5C%5C%3D1-F%282%29%5C%5C%3D%201-0.4115%5C%5C%3D0.5885)
d. Compute the expected number of withdrawals.
E(x) = np = 4
