Answer 45

A bag contains 2 white marbles and 7 purple marbles. Two marbles are drawn at random. One marble is drawn
and not replaced. Then a second marble is drawn.
a. What is the probability of selecting a purple marble and then a white marble?
b. What is the probability of selecting two white marbles?
c. Is there a greater chance of selecting two white marbles in a row or two purple marbles in a row? Show
your work

Answer 46

might be kind of easy

Answer 47

well...I know the chances of drawing a purple marble on the first try is 7/9.....and the chance of drawing a white marble on the second try is (I think) 2/8 or 1/4. So I think you just multiply them. 7/9 * 1/4 = 7/36....you will need a second opinion.

chance of drawing 2 white marbles.....2/9 * 2/8 = 4/72 = 1/18

as for the last part...I don't know about showing the work...but I believe there is a greater chance of drawing 2 purple marbles because there is more purple marbles then there is white marbles.

I am not 100% on these, it would be wise of you to get a second opinion.

Answer 48

Good-luck with these :)

Answer 49

thank you so much and thats all
