How many numbers greater than 50,000 can be formed by using the digits 2,5,5,6,7?

Explanation

To solve the problem of how many numbers greater than 50,000 can be formed using the digits 2, 5, 5, 6, and 7, we can follow these steps:

### Step 1: Calculate the total permutations of the digits
We have the digits 2, 5, 5, 6, and 7. The total number of permutations of these digits can be calculated using the formula for permutations of multiset:

\[ \text{Total permutations} = \frac{n!}{p_1! \times p_2! \times \ldots \times p_k!} \]
