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.

Graph the system of equations. {6x−4y=−244x−8y=−32 use the line tool to graph the lines.

Def rotates 90 clockwise about point a to create d’ e’ f’. therefore, which equation must be true ?
