If your teacher tells you to do questions 6 through 19 in your math book for homework, how many questions is that

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.

The difference of two numbers is 40. find the numbers if 0.3 parts of one number is equal to 37.5% of the other one.
