Math Problem Statement

Let U be the universal set, where: U=(a,bcde,f,g,h,i, Let sets A, B, and C be subsets of U, where: A=fa,b,f,h,i, ) B=la,b,c,d,f,h) C= lb,c,d,e,g,h, )

List the elements in the set (AnC) U (Bn A)

Solution

Let's solve the problem step by step. We're given:

  • Universal set U={a,bcde,f,g,h,i}U = \{a, bcde, f, g, h, i\}
  • Set A={a,b,f,h,i}A = \{a, b, f, h, i\}
  • Set B={a,b,c,d,f,h}B = \{a, b, c, d, f, h\}
  • Set C={b,c,d,e,g,h}C = \{b, c, d, e, g, h\}

We need to find the elements in the set (AC)(BA)(A \cap C) \cup (B \cap A).

Step 1: Find ACA \cap C

The intersection of sets AA and CC (i.e., elements common to both sets): AC={b,h}A \cap C = \{b, h\}

Step 2: Find BAB \cap A

The intersection of sets BB and AA (i.e., elements common to both sets): BA={a,b,f,h}B \cap A = \{a, b, f, h\}

Step 3: Find (AC)(BA)(A \cap C) \cup (B \cap A)

Now, take the union of the results from the previous steps: (AC)(BA)={b,h}{a,b,f,h}={a,b,f,h}(A \cap C) \cup (B \cap A) = \{b, h\} \cup \{a, b, f, h\} = \{a, b, f, h\}

Final Answer:

The elements in the set (AC)(BA)(A \cap C) \cup (B \cap A) are: {a,b,f,h}\{a, b, f, h\}


Would you like more details or have any questions?

Here are 5 related questions to expand on this:

  1. How would the result change if sets AA, BB, or CC were modified?
  2. Can you explain how the union and intersection operations work on sets?
  3. What happens when we take the intersection of more than two sets?
  4. How do you find the complement of a set relative to the universal set?
  5. How would the solution change if we were asked to find (AB)C(A \cup B) \cap C?

Tip: When working with sets, Venn diagrams can be very useful for visualizing operations like union and intersection!
