In one experiment, we want to evaluate the performance of the contestants of an International Geometry Olympiad. We randomly select a group of 19x contestants from different categories. The points out of 100) of the contestants are given in the table below. . - 20 30 40 / 60 70 80 Points out 50 - 90 - of 100) 60 100 30 40 50 70 80 90 Number of X- X/3 2X+1 4 11 8x 10 contestants 2
