    Step-by-step explanation:

    let p = growth probability = 60/100 = 0.6

    q = probability of not growing = 1-0.6 = 0.4

    Bernoulli equation is used to finish the probability

    if exactly one grows, then 9 does not grow

    That would be;

    P (x = 1) = 10C1 p^1 q^9

    = 10 * 0.6^1 * 0.4^9 = 0.001572864 = 0.0016 to 4 d. p
