there is no guarantee that the 5 rolls of a d4 will produce a sequence that contains a 4. Mind you this is an incorrect assumption, thus my confusion.

Um... no it's not (an incorrect assumption). There IS no guarantee that 5 rolls will produce a 4. In fact, In fact there's a 24% chance you won't get a 4 in 5 rolls of a d4.

WOW, who would have guessed such a large thread on something that is actually very trival!

I'm glad to know that there are thos on this board with the math skills and the willingness to help those of us who are probability challenged!
