Bill has a bag that contains 10 clear marbles and 5 blue marbles. He randomly draws 2 marbles, one after the other. What is the probability that the first marble is clear and the second marble is blue if the marbles are drawn (a) without replacement?
(b) with replacement?

b is the answer that makes most sense

step-by-step explanation:

89

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
