A jar contains 10 red marbles, 18 blue marbles, and 12 white marbles. Which multiplication will help you find the correct probability of picking a red marble, followed by a blue marble? (the red marble is not replaced once picked.) * 2 points

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.
