Step-by-step explanation:

In probability theory, the complement of an event A is the event not A; this complementary event is often denoted A’ or Ac. Let’s illustrate with a few examples.

If our event A is “it rains today,” then the complement, A’, is the event “it doesn’t rain today.” If you’re drawing a card from a standard 52-card deck, and the event A is “you draw a diamond,” then the complement A’ is “you don’t draw a diamond.”
