On a roulette wheel, half of the slots numbered 1 through 36 are red and half are black. Two slots numbered 0 and 00, are green.What are the odds against a ball landing in a red slot on any spin of the wheel?

Answer 1

Hey it's me again the only thing I forgot to mention is that I know that half of the slots that are red is 18/36 because 18 is half of 36 so the answer will be 3/6=1/2. The final answer will be 1/2 right or am I wrong? Please don't ignore me!!! :(

Answer 2

with 0 and 00 , there are 38 slots

18 red , 20 not red

odds against red ... 20:18 = 10:9

Answer 3

21:19
