Just a piece of advice, I suggest that you take the time to read and understand the topic assigned to you because those are fundamental concepts that you'll be using in other topics such as probabilities and college math.

Step-by-step explanation:

1.  A set is any collection of objects. Correct answer is D.

2. In a set, the elements should only be listed once. That is why the correct answer is D.

3. Looking at the elements within the set carefully, they represent prime numbers that are less than 20. Thus, the correct answer is C.

4. "The set of elements that are in P or Q or in both P and Q?" represents the union of P and Q or both (P ∪ Q). Thus, the correct answer is D.

5. A ∩ C is the intersection of elements that are common in both A and C: {1, 3, 4, 5 } (Correct letter: C).

6. A - C: This reads "A minus C," or "A complementary C" = The only element in A that is not in C is {7}. Therefore, the answer is B. {7}

7. Option A has no comon elements, because the two circles represent disjoint events.

8. A ∪ B is the union of A and B where {x|x∈A or x ∈ B (or both)}

I suggest that you really take the time to learn the set operations of Venn Diagrams, because you'll be dealing with this same topic in the near future when you guys start covering probabilities.

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%
