  1. You have to find the total number of computers to find the denominator: 72 + 112 + 711 = 895.
  2. To find the probability, you just have to set the number of the different kinds of computers as the numerator:
  • 72/895 = 0.080
  • 112/895 = 0.125
  • 711/895 = 0.794

HOPE THIS HELPED YOU :)

total number of computers =895 then plug in the the other types of computers and use as the denominator to find probability
