How to find the probability of an inclusive event?
Inclusive events are events that can happen at the same time. To find the probability of an inclusive event we first add the probabilities of the individual events and then subtract the probability of the two events happening at the same time. What is the probability of drawing a black card or a ten in a deck of cards?
How to calculate the probability of two independent events?
When we determine the probability of two independent events we multiply the probability of the first event by the probability of the second event. $$P(X \, and \, Y)=P(X)\cdot P(Y)$$. To find the probability of an independent event we are using this rule:
Which is the correct range for the probability of an event?
The probability of an event, which informs us of the likelihood of it occurring, can range anywhere from 0 (indicating that the event will never occur) to 1 (indicating that the event is certain). For any event A, 0 ≤ P (A) ≤ 1.
When is the probability of getting 3 4s?
The probability of getting 3 4s is: When the outcome affects the second outcome, which is what we called dependent events. Dependent events: Two events are dependent when the outcome of the first event influences the outcome of the second event.
Inclusive events are events that can happen at the same time. To find the probability of an inclusive event we first add the probabilities of the individual events and then subtract the probability of the two events happening at the same time.

What is the probability of an impossible event?
The probability of a sure event is always 1 while the probability of an impossible event is always 0.
When is an event an independent event in probability?
If the occurrence of any event is completely unaffected by the occurrence of any other event, such events are known as an independent event in probability and the events which are affected by other events are known as dependent events.
What is the probability of getting a specific number?
It depends on the range of the random number generator. For example, if the range is 1 through 9, the probability of getting a specific number is 1/9.
