Think About the Process The length of cell A is 6x 10-6 m. The length of cell B is 0.0000003 m. What is the ratio of cell A's length to cell B's length? Use pencil and paper. Is it easier to find the ratio
when the numbers are expressed in scientific notation or in standard form? Explain your reasoning.
The ratio of cell A's length to cell B's length is I.
(Type the ratio as a simplified fraction.)

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.
