    P = 0.1654

    Step-by-step explanation:

    Binomial probability:

    P = nCr pʳ qⁿ⁻ʳ

    where n is the number of trials,

    r is the number of successes,

    p is the probability of success,

    and q is the probability of failure (1-p).

    P = ₂₅C₁₈ (0.75) ¹⁸ (0.25) ²⁵⁻¹⁸

    P = 480,700 (0.75) ¹⁸ (0.25) ⁷

    P = 0.1654
