Answer:

Option A - 0.73

Explanation:

Given : The probability of a certain event occurring is 0.27 →P(A)=0.27

To find : The probability that the event will NOT occur →
P(A^c)

Solution: Since we know the sum of probability is 1

According to rule of complement →
P(A^c) + P(A) = 1

P(A)= 0.27 , put value we get

P(A^c) + 0.27 = 1

$\rightarrow P(A^c)= 1-0.27$

$\rightarrow P(A^c)=0.73$

Therefore, option A is correct

Probability that the event will not occur= 0.73
