A badminton player plays 5 matches. His probability of winning any single match is 0.6. The probability he wins exactly 3 matches is:

  • A. 0.2160
  • B. 0.3456
  • C. 0.4320
  • D. 0.6000

Answer: B) 0.3456

Explanation: n=5, p=0.6, q=0.4, r=3. P(X=3) = ⁵C₃ (0.6)³ (0.4)² = 10 × 0.216 × 0.16 = 0.3456.
