Range of probability values (mathematical expression)

0≤P(E)≤10 \leq P(E) \leq 1

Probability value when event cannot occur

00

Probability value when event is certain to occur

11

Probability value for even chance (equally likely)

0.50.5

Sum of all probabilities in an experiment

11

What is complementary event E‾\overline{E}?

All outcomes NOT in event EE

Notation for complement of event EE

E‾\overline{E} (E bar)

Formula: P(E)+P(E‾)=?P(E) + P(\overline{E}) = ?

11

Formula for P(E‾)P(\overline{E}) in terms of P(E)P(E)

P(E‾)=1−P(E)P(\overline{E}) = 1 - P(E)

Key word indicating use of complement formula

Not
