Question

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

Answer 1

give numbers wich is an irrational number

Answer 2

Given:

Probability of occurrence of an event = 45% = 0.45

To find:

The probability of non-occurrence of the event

Calculation:

we know that, the sum of probabilities of all the possible outcome should be equal to 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 the event is 55%
