Question 12(multiple choice worth 5 points) (07.01 mc) 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?

50% because there are originally 18 chips in the bag and 9 of them are pink. After drawing a pink chip, she replaces it and draws again (still a 50% chance).

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
