Introduction of Probability Some terms Related To Probability
Answers
Answer:
The probability of an event A is written P (A ). The probability of any outcome is the long-term relative frequency of that outcome. Probabilities are between zero and one, inclusive (that is, zero and one and all numbers between these values). P (A ) = 0 means the event A can never happen.

Answer:
Probabilityis the measure of uncertainty of any event (any phenomenon happened or bound to happen). Before we dive into the world of understanding the concept of Probability through the various formulas involved to calculate it, we need to understand few crucial terms or make ourselves familiar with the terminology associated with the Probability.
Step-by-step explanation:
The probability of any outcome is the long-term relative frequency of that outcome. Probabilities are between zero and one, inclusive (that is, zero and one and all numbers between these values).
P
(A) = 0
means the event
A
can never happen.
P
(A) = 1
means the event
A
always happens.
P
(A) = 0.5
means the event
A
is equally likely to occur or not to occur. For example, if you flip one fair coin repeatedly (from
20 to 2,000 to 20000
times) the relative frequency of heads approaches
0.5
(the probability of heads).
