You are watching: What is the probability of a certain event?
Probability: Because all the students in the class are girls, the teacher is specific to select a girl.
In the initially experiment, it was not possible to land on purple. This is an example of an impossible event. In the second experiment, picking a girl was specific to happen. This is an instance of a particular event.

Probability: Choosing a red marble is specific to happen because all 15 marbles in the jar are red. This is a specific occasion.
Summary: The probability of an occasion is the measure of the possibility that the event will take place as a result of the experiment. The probcapability of an event A, symbolized by P(A), is a number between 0 and also 1, inclusive, that procedures the likelihood of an event in the adhering to way:If P(A) > P(B) then occasion A is even more likely to take place than event B.If P(A) = P(B) then events A and B are equally most likely to occur.If occasion A is impossible, then P(A) = 0.If occasion A is particular, then P(A) = 1.
