The answer to the statement made by penny that  there are 4 ways to make 26 using 10 and 1 is; Not correct

Permutations and combinations

She wants to make 26 with only 10's and 1's

Now, the combinations to get 26 with only 10 and 1 are as follows;

10 + 10 + 1 + 1 + 1 + 1 + 1 + 1 = 26

10 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 26

1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 26

Thus, we see that there are only 3 ways and so Penny is wrong
