Answer:
There are 10 odd numbers: {1, 3, 5, 7, 9, 11, 13, 15, 17, 19} There are 4 factors of 8: {1, 2, 4, 8} There is 1 number in both lists: {1} Probability of an odd or a factor of 8 = (10 + 4 - 1)/20 = 13/20
Sorry man but I have no idea you could try google
Use the ! tool to find the # of combinations.
8!/5! = 40,320/120 = 336
