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

\(P(a_2)+P(not a_2)=1\)

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.
