So this includes the occurance that of the 5 dice.
both #1 and #4 appear once together
both #1 and #4 appear twice together
both #1 and #4 appear not at all
Can you think of any other ways?
If five balanced dice are rolled, what is the probability that the number 1 and the number 4 will appear the same number of times?
I know that n=5, but I can't figure out what other numbers to plug into the equation. 1 can appear once and 4 can appear once, or 1 can appear twice and 4 can appear twice. Anyone know how to do this??? The answer in the book is (2424)/(6^5)
Thanks in advance!!
