If we put five math, six biology, eight history, and three literature books on a bookshelf at random, what is the probability that all the math books are together?

To solve you, find the probability of five items being in consecutive order of a sample size of (5+6+8+3). 5 out of 22 items must be in a contiguous group in any order among the 22 total items.
