A total of 80 numbers 1 to 80 , you pick 4, they draw 20 from the 80, what are the odds the 4 numbers come out 🤔

80 choose 4 divided by 80 choose 20.
Im not motivated enough rn to actually do the calculations or grab a calculator.

@notavery 80 is to distract you so it's nCr(20, 4)

@SW-User that would just give you the number of ways to pick 4 from 20. That's not a probability or odds

SW-User

@notavery nah they literally said what are the odds and from 20 draws u need 4/4

@SW-User there's no way that's the odds. That's just the number of ways you get the desired outcome. Odds are the number of ways you get the desired outcome divided by the number of ways you do not.

@notavery nah thats the literal formula there, 80 is just mentioned bc its a trick Q

@SW-User so if you repeat this 4846 times, 4845 times the 4 cards you chose show up at the end and one time they dont. That makes no sense.
