Every day, artists at Arnold's House of Fine Figurines produce 5 miniature statues that must be sanded and painted. Past experience has shown that 10% of the statues have a defect that does not show up until after the statue has been sanded and painted. Whenever a statue is found to have this defect, Arnold must pay a specialist $20 to correct the defect and repaint the statue.
Describe the probability distribution for the daily amount that Arnold must pay the specialist, and determine the average daily amount the specialist will receive.
