    A spinner is divided into 4 equal sections numbered 1 to 4. The theoretical probability of the spinner stopping on 3 is 25%. Which of the following is most likely the number of 3s spun in 10,000 spins?

    We want Expected Value of s spins. Set up the expected value formula for any number 1-4
    E(s) = 0.25 * n where n is the number of spins.

    Using s = 3, n = 10,000, we have:
    E(10,000) = 0.25 * 10,000
    E(10,000) = 2,500
