# The Probability of Rolling a Large Straight with 5 Six-Sided Dice [duplicate]

I don't know the probability of rolling a large straight with 5 six-sided dice, so I need to know what the probability is. What is it?

• Matthew Conroy, it's about getting different consecutive numbers on every die in different ways – user111236 Nov 26 '13 at 4:53
• But now I know! It's a 48 in 7,776 chance of rolling a large straight. – user111236 Nov 26 '13 at 15:04
• I hope this answer is right, you know, the probability comment that's above this one that I answered yesterday (Tuesday, November 26, 2013). Also, why should comments typed in by yourself be edited up to 5 minutes? – user111236 Nov 27 '13 at 15:06

The probability of rolling 1-2-3-4-5 in that order is $(1/6)^5$. However any order will do, so it's $5!(1/6)^5$.
The probability of rolling 2-3-4-5-6 is similarly $5!(1/6)^5$.
Combining, we get $240(1/6)^5\approx 0.03$, i.e. about 3% of the time.
