M = {e, g, j}
A = {c, f, g}
You asked:
Given the below definitions for sets:
\[\begin{align*}& M &=& \left\{e, g, j\right\} \\ & A &=& \left\{c, f, g\right\}\end{align*}\]Evaluate each set by simplifying it and computing its cardinality, and evaluate the union and intersection of all given sets.
MathBot Answer:
The set is already an enumeration of its elements: \[\begin{align*} &\{e,g,j\}\end{align*}\]
The cardinality of the expression is $3$.
The set is already an enumeration of its elements: \[\begin{align*} &\{c,f,g\}\end{align*}\]
The cardinality of the expression is $3$.
The solution to the expression $M \cup A$ is the set \[\begin{align*} &\{c,e,f,g,j\}\end{align*}\]
The cardinality of the expression is $5$.
The solution to the expression $M \cap A$ is the set $\left\{g\right\}$.
The cardinality of the expression is $1$.
