AP Statistics – Simulation Exercise
The following problem was from the 2004
American Mathematics Competition.
Select numbers a and b between 0 and 1
independently and randomly, and let c be
their sum. Let A, B and C be the results when
a, b and c, respectively are rounded to the
nearest integer. What is the probability that
A + B = C?
One way to determine this probability would
be with a simulation – if we do enough
repetitions, the results should approximate
the actual probability.
Enter these commands on your screen exactly as you
see here.
When you separate commands by a colon (ALPHA
period key) this is called concatenation. If you
concatenate the commands, then each time you
press the ENTER key, you perform another 200
repetitions.
Probability that A  B  C is
