Final answer:
In flowcharts, the symbol normally used for an assignment is the assignment operator ':='.
Step-by-step explanation:
In flowcharts, the symbol normally used for an assignment is b. := (Assignment operator). This symbol indicates that a value is being assigned to a variable. In other contexts, such as programming, you might see different symbols for assignment, such as the equals sign =. It's important to differentiate the assignment operator from others like the equality operator ==, which is used to compare two values for equality but not for assignment purposes.
