JME function reference

This variable is an interactive HTML node. Interactive HTML nodes can not be relied upon to work correctly when resuming a session - for example, attached event callbacks will be lost, and mathematical notation will likely also break.

If this causes problems, try to create HTML nodes where you use them in content areas, instead of storing them in variables.

Description

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Advice

$A \cup B$ is true if $A$ is true or $B$ is true, or both.

So the corresponding column in the truth table is as follows:

{filled_table_or}

The third column combines $A \cup B$ and $B$ . Use the truth table for logical implication, $\implies$ :

{implication_truth_table}

The column $A \cup B$ in our table corresponds to $A$ in the table for implication, and the column $B$ in our table corresponds to $B$ in the table for implication.

So the completed truth table is as follows:

{filled_table}
