It is not 97% of 200 but 97% of the total number of people until the chips run out. Inother words I calculated a total of 203 people so .97 x 203 x 5 = 984. then .03 x 203 x 2 = 12 and .01 x 203 = 2 for a total of 998. So there must have been 204 people.wrong Total
204 x .97 x 5 = 989 989
204 x .03 x 2 = 12 1001
204 x .01 x 1 = 2 1003
