That is written verbally.
In standard form, that would be:
d + 12 / 3
Answer: The correct option is (1) Dependent.
Step-by-step explanation: For two events, we are given the following values of the probabilities :
P(A ∩ B) = 0.20, P(A) = 0.49 and P(B) = 0.41.
We are to check whether the events A and B are independent or dependent.
We know that
the two events C and D are said to be independent if the probabilities of their intersection is equal to the product of their probabilities.
That is, P(C ∩ D) = P(C) × P(D).
For the given two events A and B, we have

Therefore, the probabilities of the intersection of two events A and B is NOT equal to the product of the probabilities of the two events.
Thus, the events A and B are NOT independent. They are dependent events.
Option (1) is CORRECT.
Answer:
2. 33.25
Step-by-step explanation:
In order of operations you start with the part of the equation that is in parentheses. So here you would start with 8.7+4.6. Now whenever there is a number just sitting outside the parentheses, you multiply it by the numbers inside of the parentheses. So in this case, once you've added 8.7 and 4.6, you multiply your answer by 2.5 (which is outside of the parentheses. Here is the solving process:
2.5<u>(8.7+4.6)</u>
<u>2.5(13.3)</u>
33.25
