1: a dice has 6 side. so 1/6 to get 1 number on 1 dice. so each dice has 1/6, 1/6,1/6, 1/6,1/6, 1/6. you do the math. its your hw.
2: 15 men, 10 women. total of 25 ppl. chance that 1 women gets pick is 1/25. but what about 5 women? you do the math.
3: 8 runners. 4 from each school. chance that west is 1st is 1/8. chance that west is 2nd too is now 1/7. so theres 2 west and 4 central runner left. total of 6 runners. you do the math. good luck.
