• To find both types of coins, we can model the process as drawing from a set of two distinct items.

• The expected number of draws to get both types can be calculated using the formula: E = n * (1 + 1/2 + 1/3 + ... + 1/n).

• For 2 types of coins, the expected number of picks is E = 2 * (1 + 1/2) = 3.
