### Brain Teasers

# One Out of Six

Trick
Trick brain teasers appear difficult at first, but they have a trick that makes them really easy.

Rolling three once on a regular die is 1/6 likely. Rolling three twice in a row on a regular die is 1/36 likely. How likely is it that your next roll on the same die will be a three?

### Hint

This is not the same as asking how likely it is that you'll roll the die three times and get three on all of those rolls.### Answer

It is 1/6 likely.Hide Hint Show Hint Hide Answer Show Answer

Good Teaser, Had to use the hint to get it.....

not so hard I got it on my own not so fu to do

I hope this gets corrected quickly! It doesn't look good to have had this maths approved. Two consecutive 3s has a probability of 1/36, not 1/12. An easy but still fun, standard question.

Yes, I agree with the above poster.

A bit easy, but it made me think. I didn't use the hint, but if one had, they would have gotten the teaser very fast.

Well, it's nice to have another Trick teaser. This category doesn't get very many new ones.

Someone is already correcting it for me. Happy Easter everyone!

the law of averages......

Uhh... I've seen this teaser way before it appeared here...

not the best 1, but who am i to judge?

Keep Life Simple. 1/6 Makes Sense for the situation, but for Pure Math, maybe not.

Good job..

Good job..

At first I thought is 1/12... Now it's actually 1/6 Great teaser!

Very easy, I think the hint gives too much away.. although i solved it without

I still dont get it..........not a math guy.

Pretty easy. I got it right away.

yay! trick teasers are my favorites because I always get them right and if I miss one I'm like oohhhhhh. luckily I got this right even without the hint.

I don't understand it at all,and i'm the smartest girl in TEXAS!!!!!!!!!!!!!!!

Haha, figured it out.

The chances doesn't mean it happened.

You might get a 1 at the first time, and a 4 in the second, he didn't say "3 three times in a row", he just said "a 3 the third time"

Anyone understands what i'm saying? :/

I love tricks. They can be so easy!

Close to a year after it's been made and it still hasn't been corrected. 1/6*1/6 = 1/36, not 1/12. Did the people who approved this teaser pass grade 10 math?

i thought it was 1/6 then i thought i was wrong but i was right!

Yes, someone please correct the math here.

Sorry guys, I don't know what's taking so long...

I just thought they were trick dice.

2nd comment and 3rd comment look at last sentence carefully. it doesnt say3 consecutive threes,it says a three.

oh

It does say that it's 3 consecutive rolls.

"Rolling three twice in a row" and "your next roll" imply that all three rolls are consecutive. The maths is wrong.
