210-255 · Question #121
Which type of analysis shows what the outcome is as well how likely each outcome is?
The correct answer is C. probabilistic. Probabilistic analysis differs from other analysis types by quantifying both the possible outcomes and the likelihood (probability) of each occurring.

Why each option
Probabilistic analysis differs from other analysis types by quantifying both the possible outcomes and the likelihood (probability) of each occurring.
Exploratory analysis is used to discover unknown patterns or relationships in data and does not assign probabilities to outcomes.
Descriptive analysis summarizes historical data to explain what has already occurred, without modeling future outcome likelihoods.
Probabilistic analysis explicitly incorporates probability into its results, meaning it does not just identify what could happen but also assigns a likelihood to each possible outcome. This makes it useful for risk assessment and decision-making under uncertainty. Deterministic analysis, by contrast, produces a single fixed result without any probability weighting.
Deterministic analysis assumes fixed inputs produce a single, certain output with no probability distribution across outcomes.
