Coach Gladney has a bag of 17 colored chips: four are blue, 6 are green, 2 are red and the others are yellow. What is the probability of drawing a blue-chip, replacing it, and then drawing a yellow chip?

Can someone answer these problems for me

If rt is greater than ba, which statement must be true ?

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.
