Khi John lấy 5 quả bóng, kết quả có thể là 3 xanh và 2 đen. Chưa được 4 quả cùng màu.

Trong 3 loại đỏ, trắng, vàng còn lại, John phải lấy thêm ít nhất 10 quả nữa để chắc chắn có 4 quả cùng màu vì: 10 chia 3 bằng 3 dư 1. 4 quả ấy bao gồm 3 quả là Thương cộng 1 quả là Dư.

Vậy John phải lấy ít nhất 15 quả bóng để chắc chắn có 4 quả cùng màu.

The number of ways is : \(\frac{9\cdot8\cdot7\cdot6\cdot5}{120}=126\) ( ways )

Ans:126 ways
