Bài 1: Một cái hộp đựng 6 viên bi đỏ và 4 viên bi xanh.Lấy lần lượt 2 viên bi từ cái hộp
đó.Tính xác xuất để viên bi được lấy lần thứ 2 là bi xanh.
Hướng dẫn
* Số cách lấy lần lượt 2 viên bi từ hộp là 10.9 = 90 (cách)
* Nếu lần 1 lấy được bi đỏ và lần 2 lấy được bi xanh thì có 6.4 = 24 (cách)
* Nếu lần 1 lấy được bi xanh và lần 2 cũng là bi xanh thì có 4.3 = 12 (cách)
Xét các số có 9 chữ số khác nhau :
- Có 9 cách chọn chữ số ở vị trí đầu tiên
- Có A89 , cách chọn 8 chữ số tiếp theo
Do đó số các số có 9 chữ số khác nhau là 9 . A89 = 3265920
- Có C45 cách chọn 4 chữ số lẻ .
- Đầu tiên ta xếp vụ trí cho chữ số 0 , do đó chữ số 0 không thể đứng đầu và cuối nên có 7 cách xếp
- Tiếp theo ta có A24 cách chọn và xếp hai chữ số lẻ đứng 2 bên chữ số 0
- Cuối cùng ta có 6! cách xếp 6 chữ số còn lại vào 6 vị trí còn lại
Gọi A là biến cố đã cho , khi đó n(A) = C45 . A24 . 6! = 302400
Vậy xác xuất cần tìm là : P(A) = 302400/3265920 = 5/54
hắt xì ! thằng nào kêu mình !
