Question

probability of an event e + probability of event note​

Answer 1

Answer:

A sure event has probability 1 and an impossible event has probability 0

Hence probability of any event has to be either 1, 0 or a value between 0 and 1

Hence probability of an event e + probability of an event e not = 1

Answer 2

Answer:

1

Step-by-step explanation:

for every event there is chance of it occurs or not occurs

so the total probability can be written sum of the probabilities of the event occur and event not occurring

there fore

probability of an event e + probability of event e not = total probability

we know total probability is always 1

hence

probability of an event e + probability of event e not =1

HOPE IT IS HELPFUL
