The question may seem irrelevant but I really need the answer.


If I have six dice, five of them are normal dice, but the sixth dice is blank on five sides and has a six on one side. What are the odds of rolling a straight?

Thanks in advance

(1/6)*(5/6)*(4/6)*(3/6)*(2/6)*(1/6)=5/1944 = 1 in 388.8

What do you mean by a straight? length 6 (s6)? length 5 (s5) as in poker?
miplet’s answer looks correct for s6, p(s6) = 5!/6^5 = 5/1944, but the odds should be (1944-5)/5 or 387.8/1.
On the other hand, p(s5) = 2p(s6) because there are two possibilities, 123456 and 234566. Odds (1944-10)/10 or 193.4/1.
