If A and B are independent events, P(A and B) =

Answers

Answer:

If A and B are independent events, then the events A and B' are also independent. Proof: The events A and B are independent, so, P(A ∩ B) = P(A) P(B). From the Venn diagram, we see that the events A ∩ B and A ∩ B' are mutually exclusive and together they form the event A.

Answer:

Step-by-step explanation:

Given A and B are independent events, P(A and B) = P(A)*P(B)

If A ⊂ B, then A ∩ B = A ∪ B. always, sometimes, never

Answers

Answer:

Hence, the property:

            A ∩ B = A ∪ B never hold .

Step-by-step explanation:

We are given that set  A⊂B .

This means that set A is properly contained in set B.

i.e. A≠B

This means that there are some elements in set B which are not in set A.

Now we have to show whether the following property A∩B=A∪B

always, sometimes or never hold.

As A is a proper set of B.

This means that: A∩B=A ( Since A is a smaller set)

Also, A∪B=B  (Since B is a bigger set)

                   Hence, A∩B ≠ A∪B  (Since A≠ B)

The answer is never.

Answers

Answer:

b = 2

c = 6

Step-by-step explanation:

  • the possible value of c = 6 or 8 (positive, even, single-digit number & higher than a)
  • a = 4

[1]

a + b = c

4 + b = 6

b = 2 (meet all requirements)

[2]

a + b = c

4 + b = 8

b = 4 (not valid, because a = b)

b = 2

c = 6
