Which of the following best describes the relationship between the binomial (x - 1) and the polynomial x3 - 1?

a. (x - 1) cannot be a factor because x3 - 1 is not quadratic.
b. (x - 1) is not a factor.
c. (x - 1) is a factor.
d. it is impossible to tell if (x - 1) is a factor.

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.
