First dozen (wins if any of the numbers 1-12 come up) or second dozen (wins on 13-24)

The casino game roulette. In this game, the dealer spins a marble around a wheel that contains 38 pockets that the marble can fall into. Each pocket has a number (each whole number from 0 to 36, along with a double zero) and a color ( 0 and 00 are both green; the other 36 numbers are evenly divided between black and red). Players make bets on which number (or groups of numbers) they think the marble will land on. The figure shows the layout of the numbers and colors, as well as some of the bets that can be made.

What is the probability of winning at least one of the following pairs of bets on a single spin of the wheel?
