# S-290 PingPong Ball
#
# The following R program was designed for use in cold calling in a
-# class room environment. It takes a list of options, selects one at
-# random and returns it, and then adjusts the weights so that the
-# selected option is relatively less likely to be selected in the next
-# draw.
+# class room environment that tries to balance true randomness with
+# the desire to spread questions out.
