Answer:
Option A - 0.73
Step-by-step 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 → [tex]P(A^c)[/tex]
Solution: Since we know the sum of probability is 1
According to rule of complement → [tex]P(A^c) + P(A) = 1[/tex]
P(A)= 0.27 , put value we get
[tex]P(A^c) + 0.27 = 1[/tex]
[tex]\rightarrow P(A^c)= 1-0.27[/tex]
[tex]\rightarrow P(A^c)=0.73[/tex]
Therefore, option A is correct
Probability that the event will not occur= 0.73
