9 dimes

Answer 2

Well, the first coin has chance
`(20)/(29)` to be a penny. When it is a penny, the only valid case (the other case gives 0 for the multiplications later, so it is ignored) gives
`(19)/(28)` chance for the second one to be a penny. The result is
`(20*19)/(29*28)`, which is
`(95)/(203)`, or about 46.80% (rounded to the first 2 decimals)
