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
