Answer:  

The correct option is D. 0.46

Step-by-step explanation:

P(A) = 0.19

P(B) = 0.27

Now, Both the events A and B are given to be mutually exclusive

⇒ P(A ∩ B) = 0

Now, We need to calculate P(A or B)

⇒ P(A or B) = P(A) + P(B)

⇒ P(A or B) = 0.19 + 0.27

⇒ P(A or B) = 0.46

Hence, The correct option is D. 0.46
