Answer 2

Answer:

20

Step-by-step explanation:

If the order matters, we can use the product rule to show each of the $20$ coins can be chosen in $5$ ways, for a total of $5^{20$ ways, assuming you have enough of each type of coins.

If the order does not matter (which in the case it probably does not) you have to use an r-combination. The formula is$C(n+r-1,r)$. Here $n=5$ and $r=20$. So we get $C(24,20)$.
