Please help me with 1-4. I will give an Brainly and a bunch of extra points.

Answer:

$\sf 1) \quad \sf A \cup C = \{a, b, c, d, e\}$

$\sf 2) \quad B \cap A = \{a, b, d\}$

$\sf 3) \quad B' = \{c, f, g, h \}$

$\sf 4) \quad A -(B \cap C') = \{a, c \}$

Step-by-step explanation:

Set Notation

$\begin{array}{|c|c|l|} \cline{1-3} \sf Symbol & \sf N\:\!ame & \sf Meaning \\\cline{1-3} \{ \: \} & \sf Set & \sf A\:collection\:of\:elements\\\cline{1-3} \cup & \sf Union & \sf A \cup B=elements\:in\:A\:or\:B\:(or\:both)}\\\cline{1-3} \cap & \sf Intersection & \sf A \cap B=elements\: in \:both\: A \:and \:B} \\\cline{1-3} \sf ' \:or\: ^c & \sf Complement & \sf A'=elements\: not\: in\: A \\\cline{1-3} \sf - & \sf Difference & \sf A-B=elements \:in \:A \:but\: not\: in \:B}\\\cline{1-3} \end{array}$

Given sets:

U = {a, b, c, d, e, f, g, h}
A = {a, b, c, d}
B = {b, e, a, d}
C = {a, e}

Therefore:

Universal set = {a, b, c, d, e, f, g, h}
B' = not in B = {c, f, g, h}
C' = not in C = {b, c, d, f, g, h}

Question 1

$\begin{aligned}\sf A \cup C & = \sf \{a, b, c, d\} \cup \{a,e\}\\& = \sf \{a, b, c, d, e\}\end{aligned}$

Question 2

$\begin{aligned}\sf B \cap A & = \sf \{b, e, a, d\} \cap \{a, b, c, d\}\\& = \sf \{a, b, d\}\end{aligned}$

Question 3

$\begin{aligned}\sf B' & = \rm U - \sf B\\& = \sf \{a, b, c, d, e, f, g, h \}-\{b, e, a, d\}\\& = \sf \{c, f, g, h \}\end{aligned}$

Question 4

$\begin{aligned}\sf A -(B \cap C') & = \sf \{a, b, c, d \}- \left( \{b, e, a, d \} \cap \{b, c, d, f, g, h \} \right)\\& = \sf \{a, b, c, d \}- \{b, d \} \\& = \sf \{a, c \}\end{aligned}$
