Modeling part cost per unit with a Uniform distribution implies what about the likelihood of costs within the defined range?

• A. All values between 80 and 100 are equally likely.
• B. Costs greater than 100 are more likely
• C. The most likely value is 90 only
• D. Probability peaks at 80 and 100

Answer: (A)

Uniform modeling assigns equal chance to every value within the defined range. If costs are modeled as Uniform from 80 to 100, any value inside that interval is equally likely, and the probability of landing in any subrange of the same width is the same. The distribution has a constant probability density on [80, 100] and zero probability outside it, so there isn’t a single most likely value and costs above 100 aren’t considered. This is why all values between 80 and 100 are equally likely.
