The probability of an event is defined as the ratio of favourable outcomes to total outcomes. In the case of discrete distributions these will be represented by numbers, while for continuous distribution they will be measured as areas. In either case, the first measure is non-negative and the second is positive and so the probability is greater than 0. Also, the number of favourable outcomes cannot be greater than the total so the probability must be at most 1.

The value of a probability is a number between 0 and 1 So it's either positive and less or equal to one or null

no, z score can be negative but a probability is a always positive between 0 and 1.

Not necessarily. There may not even be a way to work out a theoretical probability. Furthermore, there is always a chance, however small, that the experimental probability is way off.

There is a chance that it might be.

yes.

The positive number is always greater.

2 of course. Because 2 is positive and -5 is negative and positive numbers are always greater than negative numbers.

Not always, but most of the time.

No. Negative numbers are always smaller than positive numbers.

No. Probability values always have to be positive.

yes. for all positive, distinct numbers greater than 0

-- Addition always does if both are positive. -- Multiplication does if, for example, both are positive and greater than ' 1 '. -- Exponentiation does if, for example, both the base and exponent are positive and greater than ' 1 ' .

No. Probability is always represented as a positive ratio/fraction/percent.
