Shelli, one of the Tunettes (Johnny Manta's back-up singers), loves guys who are into math. Answer her math question correctly and maybe you can win her heart, among other parts of her:

"Guavan whale harpooners area all perfect shots. Ten Guavan harpooners are in a whale boat when 10 whales swim past. All 10 harpooners pick a whale at random to throw at, and all 10 harpooners fire at the same time. How many whales could be expected to escape, on average, if this experiment were repeated a large number of times?"
