What are the odds in favor of getting a "5” on either or both dice?

With two dice, there are 36 equally likely outcomes. Getting at least one 5 gives 6 outcomes with the first die showing 5, plus 6 with the second die showing 5, minus the double-5 outcome counted twice: 6 + 6 − 1 = 11 favorable outcomes. The other 25 outcomes are unfavorable, so the odds in favor are 11 to 25, choice C.
