Given:
$5 bills
$10 bills
$20 bills
probability of $20 is 4/15
probability of $5 is 1/3
numerator is the number of events
denominator is the number of outcomes
the missing probability is of the $10 bill.
4/15 + 1/3 + x = 1 or 15/15
$5 bill = 1/3 x 5/5 = 5/15
15/15 - 4/15 - 5/15 = (15-4-5)/15 = (15-9)/15 = 6/15 = 2/5
the probability of $10 is 2/5
