Risk is defined as "A possibility of incurring loss or misfortune". So that means it doesn't always happen, which implies that it will happen a certain percentage of the time. This percentage is also known as the probability of it occurring, which means if you know the probability of the risk happening you can do a lot of things with it, such as find the expected value of the risk :)
If you were just told that it was possible that your house would burn down tomorrow, you wouldn't know what to expect, because you don't know the probability of this happening, but if you're told that something will happen with a 50% or even an 80% probability, you'll take the event more seriously.
If the probability of an event is p, then the complementary probability is 1-p.
An exposure consist of the potential financial effect of an event multiplied by its probability of occurrence and risk is with probability of occurrence. Thus an exposure is a risk times its financial consequences.
The power of a test is 1 minus the probability of a Type II error.
If events A and B are statistically indepnedent, then the conditional probability of A, given that B has occurred is the same as the unconditional probability of A. In symbolic terms, Prob(A|B) = Prob(A).
Probability is used to answer questions in the category of Statistics. Probability is a basic statistic that gives numeric value to the questions; Will a specific event occur? or How certain are you that it will occur. Probability of rolling a 3 on a 6-sided die is 1/6.
If the probability of an event is p, then the complementary probability is 1-p.

The risk associated with an event is the product of the probability of the event occurring and the hazard associated with the event.
risk is pre-stage for return...
no relationship
The power of a test is 1 minus the probability of a Type II error.
When it comes to investing, one general relationship between risk and reward is that taking more risk is associated with a greater return. However, in many cases there is no relationship between the two. For example, even though stocks tend to have a higher return than bonds, taking that risk does not guarantee a better return.
A Risk is an uncertain event or condition that if it occurs, has a positive or negative effect on a Project's Objectives. Risk Management literally refers to the management of the Projects Risk. However, the official definition is: Risk Management is the act of increasing the probability & impact of positive events and decreasing the probability & impact of adverse events within a project.
If you don't take risk, u won't gain. So, big risk, big profit.....
Probability and Impact
the risk is the probability of injury
If events A and B are statistically indepnedent, then the conditional probability of A, given that B has occurred is the same as the unconditional probability of A. In symbolic terms, Prob(A|B) = Prob(A).
