How many different ways can the manager form this core, if the team needs to have exactly two defenders on it? Correct Answer 60
Total player of in football team is 11 including 1 goal keeper is not considered. Therefore 10 players.
⇒ 6 defenders and 4 forwards = 6 + 4 = 10 comprising 5 players in core.
∴ 6 defenders in a team at least 2 defenders is exactly.
6C2 × 4C3 = (6!)/(4!) × (2!) × (4!/1!) × (3!)
⇒ (6 × 5 × 2) = 60
∴ the required answer be 60
