That will depends entirely on how the two events are related. For instance, there may be a weak correlation, or a strong correlation, between two probabilities. You really need more information, about how the events are related. There is no single simple rule.

When looking at 2 possible events how do you calculate the probability?
are they dependent or independent? define success and failure for the 2 events. probability of success (EX: drawing a face card) = number of possible successes / total possible events. Multiply the two separate probabilities to get the probability that both occur.
What the mean of unliquidated?
1.The possibility of an obligation to pay certain sums dependent on future events. 2.defined obligation by a company that must be met,but the probability of payments is minimal.
What is the probability of flipping no heads when you flip three identical coins?
The probability of flipping one coin and getting tails is 1/2. In order to find the probability of multiple events occurring, you find the product of all the events. For 3 coins the probability of getting tails 3 times is 1/8 because .5 x .5 x .5 = .125 or 1/8.
Why do complementary events always have a probability of one?
If an event is absolutely certain to happen is then we say the probability of it happening is 1.Complementary events are such that one of the events musthappen. Therefore the probability of one of a set of complementary events occurring is 1.For instance : The probability that a fair coin when tossed will come down showing heads is 1/2, and that it will show tails is also 1/2.The two events are complementary so the probability that the coin toss will result in either a heads or a tails is 1.Similarly, the probability that a die when rolled will show a number 1, 2, 3, 4, 5 or 6 is 1 as all six events are complementary.
What is Probability of Flipping a coin five times in a row and having it land on heads?
The probability of getting a heads on the first flip is 1/2. Similarly, the probability on each subsequent flip is 1/2, since they are independent events. The probability of several independent events happening together is the product of their individual probabilities.

What is the probability that a family of 2 children has exactly 2 boys?
Probability equals the number of ways an event can occur divided by the total number of events. The total number of events is (b=boy, g=girl) is bb, bg, gb, gg. The probability is then 1/4.
What is the addition rule of probability?
The addition rule of probability states that the probability that one or the other will happen is the probability of one plus the probability of the other. This rule only applies to mutually exclusive events. For example, the probability that a dice roll will be a 3 is 1/6. The probability that the dice roll will be even is 1/2. These are mutually exclusive events as the dice cannot be both 3 and even. Thus the probability of the dice roll coming up either a 3, or even, is 1/2 + 1/6 = 2/3.
How do you find the probability of a spinner?
You find out how many choices there are in a spinner and then you take what it wants you to find the probability of and tur it into a fraction For example: You have a spinner with 4 triangles in it....2 are red and 2 are green,What is the probability of landing on a green triangle 2 out of 4
What does it mean for two events to be dependent?
An even is dependent of the other when one has to occur before the other can do so. Else, one can also occur with the other. E.g. Christmas (or the winter holidays if you will) has to happen/so that/you go buy Christmas presents. Hunger usually "depends" on the lack of food in the stomach. --- In math, events are dependent when one event affects the probability of the other. E.g. There is 1 red, 1 green and 1 blue balls in a container. You pick a ball out of 3. There is a probability of 1/3 = 33% of being a certain colour. Now there are only two balls in the container. The next one you pick has a probability of 1/2=50% of being a certain colour,
What is used in probabilty when looking for the outcomes of 2 events?
Whether the events are independent or dependent, whether or not they are mutually exclusive.
What is the probability of flipping heads and rolling an odd number?
These would be independent events; therefore, we can multiply the probabilities of each of the two events. Probability of flipping a head: 1/2 Probability of rolling an odd number with a single die: 1/6 Required probability : 1/2 x 1/6 = 1/12
What is an event with a probability greater then 0 but less than half?
There are many such events. The probability of throwing a 1 or 2 on one roll of a die, for example.
