Question

probability of an event E+ probability of the event `not E=?

Answer 1

probability of an event E + probability of the event not E= 1

Answer 2

Answer:

probability of an event E + probability of the event not E=1

Step-by-step explanation:

We have to find the value of

probability of an event E+ probability of the event not E

i.e P(E)+P(E')

Probability is the extent to which an event is likely to occur.

As we know , an event and its complement are mutually exclusive and exhaustive i.e their intersection is Ф which implies in any event, either the event or its complement will happen, but not both.

As total probability is 1 which results into

The sum of the probabilities of an event and its complement is always equal to 1 i.e

probability of an event E+ probability of the event not E=1

P(E)+P(E')=1
