Insane probability question… I need a genius’s help?

Suppose you have five six-sided dice. Each die has the following letters on the faces: E, O, I, Y, K, and R.

What are the odds that, upon rolling the five dice, you would be able to spell the name of a Neopet species with some or all of the letters displayed on the dice? Assume each die can only be used once in the word; for example, if you rolled “A,A,B,C,D” you could use A twice, but B, C, and D only once.

Please submit your answer as a whole number, rounded to the nearest whole number. (i.e. if the odds are 1 in 100, submit the answer “100”.)

There are two neopet species that have those letters, Kyrii, and Eyrie.

Isn’t there also one called KOI?… a fish?

Other than that, I can’t really help. Sorry… =-(

Well there are 720 possible ways to throw the 5 dice. All you must do is figure out how many of them spell a name. Try this link, it will be helpful:
