The number of chips of different colors in Amy's bag is shown below: 8 blue chips 9 pink chips 1 white chip Amy takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Amy takes out a pink chip in both draws? (5 points) 9 over 18 multiplied by 8 over 17 equals 72 over 306 9 over 18 plus 8 over 17 equals 297 over 306 9 over 18 multiplied by 9 over 18 equals 81 over 324 9 over 18 plus 9 over 18 equals 18 over 18
ok so first you add up all the chips
18
Yes and then you should put in a fraction take will make it half
do you know how to do that?
9/18
yes correct o: and now you reduce it
know how to do that?
not really
basically divide
so divide 9/18
yes, Divide each of those numbers by the top number which is 9
2
?
no. Remember you have to keep it a fraction
or would it be 1/2 or
yes correct o:
