90%

Answer 2

Answer: 0.9

Explanation:

For any event A , the probability of event A will occur be P(A).

Then , the probability of not occuring the event A will be given by :-

`\text{P(A')=1-P(A)}`

The given statement : The probability that an event will occur is 0.1.

That is ,
`P(A)=0.1`

Now, the probability that the event will NOT occur is given by :-

`\text{P(A')}=1-0.1\\\\\Rightarrow\ \text{P(A')}=0.9`

Hence, the probability that the event will NOT occur = 0.9
