That's the probability that both events will happen, possibly even at the same time.
I think it's called the 'joint' probability.

How to calculate Risk probability?
"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.

What is the probability of choseing a king or king from a deck of 52?
The probability of getting a king in a one card draw from a deck of 52 cards is .077 or 1 chance in 13. The probability of getting a king and one other specific denomination, such as a queen, is .154, or one chance in between 6 and 7.
Because only the second toss matters and there's 2 sides it can land on, the chance your second toss will be tails; will still be 50%. If you want both coins to turn up as tails it would be 0,50 x 0,50 = 0,25 x 100% = 25% chance for both to be tails.
What does three point contact mean when using a ladder?
It means that at least three points of your body, it might be either two hand and one foot or one hand and two feet, must be in touch with the ladder while ascending or descending. So keep your both hands free, never carry anything with your hands, while climbing.
Please note that the important part is while ascending and descending. Once you arrive to the level you want to work at, you may do light work that may require both hands. Do not lean out far enough to cause your belt buckle to extend outside the side rails. THERE IS NO FALL PROTECTION REQUIRED ON LADDERS. Always follow manufacturer's recommendations.
When rolling a number cube twice what is the probability of rolling at least one even number?
one fourth
Relationship between relative frequency and probability of an event?
The relative frequency is an estimate of the probability of an event.
What is the probability of being related to someone?

also the person. these are factors
a) country
b) skin color
c) parents and other relitives
d) where you both live
A card is drawn from a pack of 52 cards The probability of getting A face card?
There are 3 face cards in a suit of 13 cards, so the probability is = 3/13.
Difference between calculating the sample mean and the population mean?
The same basic formula is used to calculate the sample or population mean. The sample mean is x bar and the population mean is mu. Add all the values in the sample or population and divide by the number of data values.
The homozygous dominant individual can only pass on the dominant allele and the homozygous recessive individual can only pass on the recessive allele, therefore all offspring will be heterozygous and have the dominant phenotype.
The probability of choosing a green marble from this jar would be 6/15. You get this answer by adding up the sum of all the marbles.
Why the standard deviation of a set of data will always be greater than or equal to 0?
Because it is defined as the principal square root of the variance.
What is the probability that 3 cards are drawn from a deck and you get 2 reds followed by a black?
The probability is (26/52)*(25/51)*(26/50) = 16900/132600 = 0.1275 (approx).
If the two events are unrelated, as they are in rolling two dice or one die twice, simply multiply the probabilities together. However, you also have to consider the permutations involved in rolling dice and realize that there is more than one way to roll a particular sum.
There are 36 permutations of rolling two dice. Of these, exactly one has a sum of two, the the probability of rolling a sum of two is 1 in 36, or about 0.02778. You simply multiply 1 in 6 by 1 in 6, getting 1 in 36. In the case of rolling a sum of seven, there are exactly six permutations, 1+6, 2+5, 3+4, 4+3, 5+2, and 6+1, so the probability of rolling a sum of seven is 6 in 36, or 1 in 6, or about 0.1667.
Another example is rolling pairs, such as two's or three's. The probability of rolling "something" on one die is 1 in 1, while the probability of matching it on the second die is 1 in 6, so you multiply (1 in 1) by (1 in 6) to get a probability of rolling a pair of 1 in 6, or about 0.1667.
More useful towards understanding this concept is a deck of 52 cards. The probability of drawing an Ace is 4 in 52, or 1 in 13, or about 0.07692. The probability of drawing two Ace's is (4 in 52) times (3 in 51), or 12 in 2652, or 1 in 221, or about 0.004525. In this case, the two events are related, because the occurrence of the first event affects the probability of the second event, so you need to consider the calculation carefully.
With Aces high, the expected gain for each draw for player "I" is -130*3/13 + 36*10/13 = (-390+360)/13 = -30/13. That is, an expected loss of 24/13
