Question

A researcher surveys 200 randomly selected college students to determine the number of education majors and mathematics majors. 16% of the students surveyed are education majors and 6% of the students surveyed are mathematics majors. 2% of the students are both education majors and mathematics majors. What percentage of the students surveyed are education majors or mathematics majors?

Answer 1

percentage of math major = 6%

percentage of education major = 16%

percentage that is both math major and eduaction major = 2%s

The percentage that are education majors or mathematic majors can be calculated below

$\text{Education majors + mathematics major = 16 + 6 -2= }20\text{ \%}$

P(M or E) = P(M) + P(E) - P(M and E)
