Feature bets

I saw a bet I hadn't seen before. You can bet All Small (2,3,4,5,6) at 35-1 or All Tall (8,9,10,11,12) at 35-1 or All (all the numbers) at 175-1. Can anyone tell me what the true odds are and how to calculate? I know how to calculate the odds on any number, like 4 is 2-1 because there are 3 fours and 6 sevens. But don't know how to calculate the feature bets. Thanx.

Analyzed by Wiz here All Small
