"Risk probability" does not quite make sense, perhaps you mean just how to calculate risk. There are many formulas and methods, a lot of them highly complex mathematical models. Risk calculation is an important subset of portfolio theory.
For the simplest cases, consider some of the following definitions:
* the greatest dive that a stock took over a given historical time period. For example, if stock A dropped 30% maximum over past 5 years before rebounding, and stock B dropped 40% maximum over the same period - then by this metric you can see that stock B is riskier.
* standard deviation of the returns over a historical time period. Take as your data set the prices a stock assumed over the last 5 years daily. You can calculate the standard deviation of this data set. The standard deviation is a measure of risk.
The answer depends on what you mean by "do". Does it mean calculate individually, calculate the probability of either one or the other (or both), calculate the probability of both, calculate some function of both (for example the sum of two dice being rolled)?

Risk
Comprise risk.
It is the risk.
You can calculate the probability of the outcome of events.

the risk is the probability of injury

A matrix that identifies a risk based on the severity and the probability of the risk happening.

First calculate the probability of not rolling a six - since there are 5 possibilities for each die, this is (5/6) x (5/6). Then calculate the complement (1 minus the probability calculated).First calculate the probability of not rolling a six - since there are 5 possibilities for each die, this is (5/6) x (5/6).

premium=(1-Recovery Rate)*(probability of default) so if the premium is 15% and the recovery rate is 30%, then you can calculate the likelihood or probability of default. It would be (.15)=(1-.30)*probability Rearranging terms you get: probability=.21428 The Recovery Rate is the percentage of your original asset you'd recover under the default circumstance.
The risk associated with an event is the product of the probability of the event occurring and the hazard associated with the event.
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.
