Helen [10]

Answer:

Johnny is wrong.

A \cup B = \left\{a,b,c,d,e,f,g,h\right\}

Step-by-step explanation:

Johnny is wrong.

A better definition would be: A \cup B is the set of all elements that belong to at least one A or B.

So, the elements that belong to both A and B, like c and d in this exercise, also belong to A \cup B.

So:

A \cup B=\left\{a,b,c,d,e,f,g,h\right\}
