Betty has a bag with 20 marbles in it. some of the marbles are blue, some are green, and some are yellow. she draws one marble at random, records the color, and returns it to the bag. hurry here is her data after 500 trials: blue green yellow 392 52 56 estimate the probability that a marble drawn at random will be blue. estimate the probability that a marble drawn at random will be green. estimate the probability that a marble drawn at random will be yellow. express each probability estimate as a fraction with 20 in the denominator.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
