Question

A and B are two events.

Answer 1

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)

$P(A|B)= \frac{P(A*B)}{P(B)}$

P(A*B) indicates P(A and B)

Using the values, we get:

$P(A|B)= \frac{0.28}{0.8}=0.35$

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)

Answer 2

Answer:

Therefore, the correct option is the second one.
