Question

What is the symbol ~, if you're trying to find the probability of ~A?

the addition probability
the probability of the event not happening
the multiplication probability
None of these choices are correct.

Answer 1

The correct choice is: the probability of the event not happening.

The symbol ~ (tilde) is commonly used to represent the negation or complement of an event. When we refer to ~A, it means "not A" or "the complement of A." In terms of probability, ~A represents the event not happening or the event A occurring.
