In order to determine if the events are independent or not we need to find the conditional probabilities.
The conditional probability of event A, given event B is denoted as P(A|B)

P(A*B) indicates P(A and B)
Using the values, we get:

Since P(A|B) is not equal to P(A) this indicates that occurrence of event B has an impact on the occurrence of event A. This shows that the two events are dependent.
Therefore, the correct option is the second one.2. A and B are not independent events because P(A∣∣B)≠P(A)
A non-negative root of a number is called Square Root
The answer is 12.1, add both 4.5 and 7.6 and you get 12.1
