Answer: 0.243.
Step-by-step explanation:
The probability in this case is approcimated by the probability distribution formula for random variables. This formula is denoted as:
P(X=r) = nCr * p^r * q^n-r
Where n = selected number to be sampled and in this case, n= 3
r = varied number of sample and in this case, r=1
P = probability of success and in this case p = 0.10
q = 1-p=1-0.1 = 0.9
P(X=1) = 3C1 × 0.1¹ × 0.9²
P(X=1) = 0.243.
