Answer 13

what happend

Answer 14

25 total correct

Answer 15

22/25 is the probability that the student has blue eyes, fair hair or both; yes

Answer 16

so that leaves 3/25 students that do not have blue eyes, fair hair, or nor both because both is included in the 22

Answer 17

so draw two circles with a third of overlap, 19 fair hair will be one side and 15 blue eye on the other side, and 3 outside of the circles because its not included

Answer 19

(19+15)-22= your overlap or both

both --> 12/25
