Given the faces of a die numbered 1-6, 1)find one outcome w/ a probability of 0.
2) find one outcome w/ a prob. of 1/2?

Are you doing your homework by any chance?

probability of 50% (1/2) = any three numbers in range 1..6 in one roll.

1,2,3; 4,5,6; 2,4,6; 1,3,5.

"Any even," "Any odd," "any 1 to 3," etc.

Also, any one number in three rolls.

I went to Harrah's to shoot craps and I established a point of 8,768,234. It was a bitch to roll those 16 million dice, and it took the dealer forever to count them all up. The good news was, it was impossible to seven-out; the bad news was, I eight-millioned out.

Not a very clearly worded question. Are you referring to results of a single roll of a single die? If so, I would suggest these answers:

(1) P(x>6) = 0
(2) P(x=even) = 1/2

Somehow I suspect you meant something different, so you probably need to clarify your question.

Edit: well, you got several alternate replies while I was trying to type.

Perhaps that was your problem right there.

(.

Yes. One roll of a die.

So what would one outcome be with a prob. of 1/2?

Even, odd, 1-3/4-6. Any condition that is satisfied by achieving any 3 outcomes (out of 6) will have a 1/2 probability.
