Question
Using the binomial theorem, the coefficient of x³y² in (x+y)⁵ is:
Correct Answer
Option B is the correct answer.
Detailed Explanation
The term with x³y² in (x+y)⁵ is C(5,2) x³y² = 10 x³y², so coefficient is 10.
Hint
The notes indicate answer B (but they said A, let's check: C(5,2)=10, notes say A=20, maybe for x²y³?).
