There are six sides to a die. If we assume that all sides have the same chance of coming up then each side has a probability of 1 in 6 or 1/6. This is the theoretical probability. Of course if the die is not perfectly shaped and weighted then it will not be 'fair' and the sides will have different probabilities of coming up.
Find all the possible outcomes and the probabilities associated with each.

The area under any probability density function including the normal distribution must equal 1, as the sum of the probabilities of all outcomes must equal 1. However, as the domain of outcomes goes from minus infinity to positive infinity, this fact is a theoretical one, and any practical problem will have cumulative probabilities less than 1.

Sum of all probabilities is 1.
The sum of the probabilities of all possible outcomes is 1.

One.
all probabilities smaller than the given probability ("at most") all probabilities larger than the given probability ("at least")

No, not in all cases or all countries.

(1) That the probabilities lie between 0 and 1. (2) The sum of all probabilities of the distribution sum up to 1.
