The aquarium is shaped like a rectangular prism with length 20 in, width 18 in, and height 10 in. Suppose water is pumped out of the aquarium at a rate of 360 in per minute. If the aquarium starts completely full, how many
minutes does it take to empty the aquarium?

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.
