Johnny the gambler tosses 6 plain dice. In order to win the jackpot he has to receive exactly 3 times a result of 5 or 6. What are Johnny's chances to win?
I'm not sure what exactly this question is asking. To win does he have to roll either 3 x 5s or 3 x 6s, or roll 3 x 5's or 6's?
Confused!

Hi dunnec3,
What is the source of this question? I ask because it's poorly-written, it doesn't include answer choices and the question isn't clearly defined (to win, does he need a sum equal to 3(5) = 15 or 3(6) = 18 OR does he need to roll three 5s or three 6s?). You might be better served by practicing with materials that better 'match up' with what you'll face on Test Day.
