Answer: Option "D" is correct.
Explanation:
Since we have given that
Probability of an event = 0.1
Probability of an event = 0.3
Probability of an event = 0.5
Probability of an event = 0.7
So, the most likely to occur is the event which has the highest probability.
![0.7>0.5>0.3>0.1](https://img.qammunity.org/2021/formulas/mathematics/high-school/ure8tf8rpeh2o6j8028p5yzsecqedd46yc.png)
So, the most likely to occur is 0.7.
Hence, Option "D" is correct.
