Answer:

Probability the first is a communications major and the second is a business major = 0.03

Step-by-step explanation:

let the total number of students be 100

Event A= Business Majors = 15%

Event B = Communication Majors = 20%

P(A) = [tex]\frac{15}{100}[/tex]   ⇒  P(A) = 0.15

P(B) = [tex]\frac{20}{100}[/tex]  ⇒ P(B) = 0.2

P( A and B) = P(A) × P(B)

                  = 0.15 × 0.2

                  = 0.03
