Three hundred high school seniors were surveyed about their intended college majors. The results are displayed in the Venn Diagr
am below. If a student is randomly selected from the group, what is the probability that they are majoring in both math and science? Round your answer to the nearest whole percent.
The sample space of the problem is 300 while the U' is equal to 100 as given. The given diagram also shows A and B separately so we can determine the part where the two coincides. The equation goes 120 + 50 + x + 100 = 300x = 30 Hence the probability is 30/ 300 or 10%
