how do I select "between 0.34 and 0.66"? I cant use <= or >=?
I believe that you have already done the computerChoice <= 0.33, so I will tell you this:
All you have to do with the else if loop is to do computerChoice <= 0.67 (or 0.66) because if you do that, it will put every number that's from 0.33 and down to the first option. Remember, if/else if/else and the others all go in order from top to bottom.
