**jAKE1214**, Monday, January 28, 2008 at 3:05pm1. 10-99 are two digits # and that mean there are 99-10+1=90 possible numbers (and of course they're all less than 100). and so from 45-90, there are 46 numbers.

2. a and b looks right. There are 9 different letters in the word PROBABILITY so it should be 9/26.

3. Count the number of repeats in each letter within the word. For example, S repeats 3 times and the total letter is 10 thus the probably to draw an S from the word is 3/10... and so on for the rest of the problem.
