Write an equation of a circle with diameter AB.
A(1,1), B(9,9)
Choose the correct answer below.
A. (x - 5)^2 + (y – 5)^2 = 32
C. (x+9)^2 - (y +9)^2 = 1
E. (x - 5)^2 – (y + 5)^2 = 32
G. (x + 5)^2 + (y-5)^2 = 32
B. (x - 5)^2 + (y – 5)^2 = 9
D. (x - 1)^2 – (y – 1)^2 =9
F. (x - 5)^2 + (y – 5)^2 = 1
H. (x + 5)^2 – (y + 5)^2 = 32
(sorry about the orientation of the answers. The picture scanned it weird)

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
