A) 987 ways
B) 346 ways
C) 600 ways
D) 200 ways
E) 134 ways

Rationale: the number of ways of selecting three english majors , two biological science majors and three engineers is : = ⁴ c ₃ * ⁶ c ₂ * ⁵ c ₃ = ( 4 * 3 * 2 ) / ( 3 * 2 * 1 ) * ( 6 * 5 ) / ( 3 * 2 * 1 ) * ( 5 * 4 * 3 ) / ( 3 * 2 * 1 ) = 4 * 5 * 10 = 200 ways . answer : d
Answer: D
