C I’m pretty sure that’s what is it
Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Probability that they were left handed P(L)= 40%
Probability that they were Democrats P(D)= 47%
So, P(L∩D) = 135 = 0.13
Now, to check whether they are independent or not.
We will find P(L) × P(D) is given by

Since P(L) . P(D) ≠ P(L∩D)
So, they are not independent.
Hence, Option 'c' is correct.
