Question 1034822
<pre>
The prime numbers on the die are 2,3,5,7
The non-primes are 1,4,6,8.  So the theoretical 
probability  of rolling a prime is 1/2, and the 
theoretical probability of rolling a non-prime 
is also 1/2. 1/2 is 50%.

For the experimental sequence of 20 rolls, I
will put P's under the prime numbers. 

3 4 5 2 7 1 3 7 2 6 2 1 7 3 6 1 8 3 5 6
P   P   P   P P P   P   P P       P P  

There are 11 primes out of 20, so the experimental
probability is 11/20 = 0.55 or 55%.
</pre>
The experimental probability of rolling a prime number is 55%, 
which is  5% more than the theoretical probability of 50%.
