MMM #24 is available now at Blinkdagger. Here's the problem:

The Problem Statement

The five songs that the blinkdagger band (Rob, Zane, Daniel, and Quan) can complete on expert are:

- Oasis - Wonderwall
- Dashboard Confessional - Hands Down
- Bon Jovi - Livin’ on a Prayer
- Wheezer - Say It Ain’t So
- Journey - Any Way You Want It
Assume the following:

- The blinkdagger band only has time to play 8 songs before they have to start working on MATLAB tutorials.
- For each of the 8 songs, the blinkdagger band randomly chooses to play a song from the 5 listed above.
- All 5 songs have an equal chance of being picked.
Question: What is the % chance that the band will have played all five songs after their session ends?
