= Event
= the number of times an event E_i occurs
= sample size or the total number of times a process occurs
=Population size or the total number of mutually exclusive and equally likely events
= a complementary event; the probability of an event A, not occurring
=probability of some event E_i occurring
=an “intersection” or “and” statement; the probability of an event A and an event B occurring
=an “union” or “or” statement; the probability of an event A or an event B or both occurring
=a conditional statement; the probability of an event A occurring given that an event B has already occurred
=test results
