To determine how many subsets with more than two elements a set with 100 elements has, let us calculate step by step:

1. Total number of subsets of a set with $n$ elements:
   A set with $n$ elements has $2^n$ subsets. For $n = 100$, the total number of subsets is: $2^{100}$

2. Subsets with 0, 1, or 2 elements:

   • A subset with $k$ elements can be chosen using the binomial coefficient $\binom{n}{k}$.
   • Subsets with:
     • 0 elements: $\binom{100}{0} = 1$
     • 1 element: $\binom{100}{1} = 100$
     • 2 elements: $\binom{100}{2} = \frac{100 \cdot 99}{2} = 495$

   The total number of subsets with 0, 1, or 2 elements is: $\binom{100}{0} + \binom{100}{1} + \binom{100}{2} = 1 + 100 + 495 = 596$

3. Subsets with more than 2 elements: The number of subsets with more than 2 elements is the total number of subsets minus the subsets with 0, 1, or 2 elements: $2^{100} - 596$

Thus, the number of subsets with more than two elements is: $2^{100} - 596$

Explanation and Summary:

This result represents the total number of subsets minus the subsets with 0, 1, or 2 elements. Since $2^{100}$ is a very large number, the subtraction $596$ has a negligible effect on the magnitude.
