Math Problem Statement

What is the minimum number of students, each of whom comes from one of the 50 states, who must be enrolled in a university to guarantee that there are at least 100 who come from the same state?

Solution

To solve this, we apply the Pigeonhole Principle, which states that if nn items are distributed among kk containers and n>kn > k, then at least one container must hold more than one item.

Step 1: Define the problem

  • There are 50 states (k=50k = 50).
  • We need to ensure at least 100 students come from the same state.

Step 2: Distribute students evenly

  • If students are distributed as evenly as possible among the 50 states, each state will have at most 99 students before exceeding 99.

Thus:

  • If each state has 99 students, the total number of students is: 50×99=495050 \times 99 = 4950 At this point, no state has reached 100 students.

Step 3: Add one more student

To guarantee that at least one state has 100 students, we add one more student to the total: 4950+1=49514950 + 1 = 4951

Final Answer:

The minimum number of students required to guarantee that at least 100 come from the same state is: 4951\boxed{4951}
