12 students: 9B, 2H, 1(other)
3 chosen
P(no B) = %283%2F12%29%282%2F11%29%281%2F10%29
......
30 children: 18B, 12G
3 chosen
P(all boys) = %2818%2F30%29%2817%2F29%29%2816%2F28%29%2815%2F27%29%2814%2F26%29
....
two dice are rolled
___1_2_3__4__5__6
1|_2_3_4__5__6__7
2|_3_4_5__6__7__8
3|_4_5_6__7__8__9
4|_5_6_7__8__9_10
5|_6_7_8__9_10_11
6|_7_8_9_10_11_12
P(sum = 8) = 5/36

5 cards chosen
P(2 Aces) = %284C2%29%2848C3%29%2F%2852C5%29
