look to previous for a
probability you can work out as

no. of prime / total no. of numbers

then x 100 for a percentages or leave as decimal
I searched Google under the key words "prime numbers" to get this:

http://wiki.answers.com/Q/What_are_all_the_prime_number_1_to_100

a. List the number of primes within that range.

b. Primes/49

c. Primes/49 - non-primes/49 = ?

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
