Answer :
Answer:
c. 97.558%
Explanation:
Options are "A. 50.0.% B. 2.442% C. 97.558% D.197.0% E. 47,442%"
Mean = μ = 1447
Standard deviation = σ = 715
Observed value = X = 2855
Using z-score formula, Z = (X - μ) / σ
Z = (2855 - 1447) / 715
Z = 1.97
P(Z<1.97) = 0.97558
P(Z<1.97) = 97.558%
So, the probability of a stock-out is 97.558%.
