Question

If the probability of an event to happen 0.45 ,then probability of event not happening

Answer 1

$question$

if the probability of an event to happen 0.45 than probability of event not happening

$\alpha nswer$

-->probability of happening event =>45/100

-->probability happening =>0.45

=>probability of non happening event =>55/100

=>hence, correct answer o. 45

Answer:

The correct answer is

55 %

Concept

Probability means possibility. it's a branch of mathematics that deals with the occurrence of a random event. the value is expressed from zero to 1. Meteorologists, as an example, use weather patterns to predict the probability of rain. In epidemiology, mathematics is employed to know the connection between exposures and also the prospect of health effects.

Given

the probability of an event to happen 0.45

To find

probability of event not happening

Step-by-step explanation:

 P(E) + P(NE) = 1

0.45 + P (NE) = 1

P (NE) = 1 – 0.45 = 0.55

So there is the probability of event not happning is 0.55 means 55 %
