How to select other random cells
 

I have a 2 part question. I want to have a 1 question survey randomly filled
out by 200 people. Column A lists the 1 questions. Columun b has ABCDE
listed in cells B6 to b10. I would like 200 samples in columns c, d, e, etc.
How do I set this up so that they randomly Coose B6 to B 10.

Second part. On another spreadsheet, I have a similar situation, but the
user has 10 answers to select from and I want them to randomly select all
that apply. How would I do this? Thanks!
