Answer:

3/8

Step-by-step explanation:

Given that

Number of clown fish = 10

Number of Angel fish = 4

Number of Puffer fish = 6

Number of Eels = 5

From the above, there exists 10 + 4 + 6 + 5 number of fishes

There exists 25 number of fishes.

Probability of picking a clown fish then is

C = 10 / 25

If the clown fish picked isn't replaced, then there exists 9 clown fishes, and 24 total fishes. This, the probability of picking another clown fish is

C = 9 / 24

C = 3 / 8

Thus, the answer is 3/8

Can you please answer my homework, its about sets.
Katyanochek1 [597]

The value of the set  (A∪C)'∩B is {9 , 12} .

A subfield of mathematical logic called set theory examines sets, which are essentially collections of objects.

  • Set theory is a discipline of mathematics that largely addresses problems that are pertinent to mathematics as a whole, despite the fact that any kind of object can be constructed into a set.
  • Set theory is founded on a simple binary relationship between an object o and a set A.
  • It is written as o A if o is a part (or member) of A. Members of a set are enumerated with commas to denote separation when describing them, or a property of those parts is enclosed in braces.
  • Sets can be associated by the membership relation since they are objects.

The given sets are:

U ={1,2,3,4,5,6,7,8,9,10,11,12,13}

A = {3,7,11,13}

B = {3,6,9,12,13}

C = {2,3,5,6,7,8}

Now B' = {1,2,4,5,7,8,10,11}

b) B'∩C = {2,5,7,8,}

c) A∪C = {2,3,5,6,7,8,11,13}

(A∪C)' = {1,4,9,10,12}

(A∪C)'∩B = {9 , 12}

Hence the value of the set (A∪C)'∩B is {9 , 12} .
