You can put this solution on YOUR website!
Whenever you want a AND b AND c . . etc.,
you must multiply the possibilities
For multiple choice,
10%2A10%2A10%2A10%2A10+=+10%5E5 possible answers
and, for true-or-false,
2%5E15 possible answers
Since each of the 2 types of questions can
be combined with any 1 of the other type, there are
10%5E5%2A2%5E15 possible answers to test
I don't have a calculator right now, so you can do math
