Dozen question on Roulette

Betting on the 1st and 2nd dozen (both amounts same). Betting at a single zero table.

So, the odds of one dozen or ther other hitting is 24/37 or .64865 Correct?

So, the question is: what are the odds of either the 1st and/or 2nd dozen to hit in six rolls

Am I right at the answer of (.64865) to the fifth power approximately 11.5% of the time this will happen.

No.

Easier to calculate how a bet can NOT win then subtract that answer from 1.

13/37 chance not hitting within ONE spin 0.351351

13/37^6 NOT hitting in 6 spins is 0.001881264
Hitting within 6 spins = 1 - 0.001881264
answer = 99.8119%

excel can set up a nice (cumulative frequency) table very quickly to give you answers for different spins.
