Key Differences
Risk and Probability are interconnected but distinguishable concepts. While Risk focuses on the potential negative outcome or the chance of harm or loss, Probability is a measure or quantification of how likely an event is to occur.
Risk is often used in contexts where there's an exposure to danger or where something valuable is at stake. On the other hand, Probability is more neutral, signifying the mathematical likelihood of any event, positive or negative.
In finance, Risk can signify the chance of financial loss or the volatility of investments, whereas Probability might be used to assess the likelihood of various market movements or outcomes.
In health and medicine, Risk might denote the chance of contracting a disease or the potential side effects of a procedure. Meanwhile, Probability could be employed to express the chance of recovery or the likelihood of a certain outcome given certain conditions.
Both Risk and Probability play crucial roles in decision-making. Understanding the Risk helps individuals and organizations prepare for potential losses, whereas understanding the Probability helps in evaluating different scenarios and making informed choices.

Given the evidence, the Probability of his innocence is high.
Risk
In simple terms, risk is the possibility of something bad happening. Risk involves uncertainty about the effects/implications of an activity with respect to something that humans value (such as health, well-being, wealth, property or the environment), often focusing on negative, undesirable consequences.
Probability
A statistical measure ranging from 0 to 1.

Probability
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
