The probability that there will be EXACTLY one five when four dice are rolled is 500/1296 = 125/324, or about 38.58%. The odds are 199 to 125 against, or about 8 to 5.

The probability that there will be AT LEAST one five when four dice are rolled is 671/1296, or about 51.77%. The odds are 625 to 671 against, or about 14 to 15.

The odds of rolling 4 ones in 5 dice are calculated by this sum.

(1/6)^4 x 5/6 where 1/6 represents the 1, being rolled 4 times, and 5/6 represents the other dice being any number but 5. This equals 1/1555.2. That means 5 out of every 7776 rolls will end up with 4 ones. (or 1 out of 1555.2 rolls)
