So 4 names went into the bowl.
If Sam is the first person selecting then the chances of him pulling out his name are 1/4. 1/4 as a percent is 25%.
The second person selecting, Pam, now only has 3 names left in the bowl. Therefore, the chances that Pam will select Sam are now 1/3. 1/3 as a percent is 33.33(repeating)%.
Does that make sense?
