Answer:
Option B is correct.
Step-by-step explanation:
We have been given the different probabilities at different point we need to find the probability of not of 2
We know that sum of probabilities is 1
[tex]P(a_2)+P(not a_2)=1[/tex]
Here, the probability that is P(a 2)=0.40
Hence, the required probability is 1-0.40=0.60
Therefore, option B is correct.
