Answer: 75%
Explanation:
The probability that demand is less than or equal to the stocking level will be calculated thus:
Underage Cost (Cu) will be given as:
= 3 × Overage Cost(Co) = 3Co
Critical Ratio for seller is given as:
= Cu/(Co+Cu)
= 3Co/(Co + 3Co)
= 3Co / 4Co
= 75%
= 0.75
Therefore, the answer is 75%.
