# Another Truth Table

Here is another truth table that shows the operands combined with an `||`

operator.

The first several columns of a truth table show all possible boolean values of the operands. In this table, the operands are relational expressions. The remaining columns show how these values are combined by the logical operators.

Operands | Boolean Expression | ||
---|---|---|---|

x < 12 | y > 10 | x < 12 || y > 10 | |

F | F | ||

F | T | ||

T | F | ||

T | T |

**Question 3:**
