Question

If the
probability of occurrence an
event is 45%.then what is the
probability of it's non-
occurence ?

0.45
1
0.55
0 ​

Answer 1

Answer:

0.55

100%-45%=55%

45/100=0.45

occurence probability=0.45

non-occurence probability=1 - 0.45 = 0.55

Answer 2

Given:

The probability of occurrence of an event = 45%  = 0.45

To find:

The probability of non-occurrence of an event

Calculation:

The sum of probabilities of occurrence of an event is equal to 1

=> Sum of probabilities = 1

=> Probability of occurrence + Probability of non-occurrence = 1

=> 0.45 + Probability of non-occurrence = 1

=> Probability of non-occurrence = 1-0.45

=> Probability of non-occurrence = 0.55 = 55%

The probability of non-occurrence of an event is 0.55
