'randomly-performed' originates from the combination of 'randomly' and 'performed', where 'randomly' is derived from 'random', meaning 'lacking a definite plan, purpose, or pattern', and 'performed' is derived from 'perform', meaning 'to carry out an action or task'.

'randomly' changed from the Middle English word 'randoun', meaning 'impetuous rush', and 'performed' evolved from the Old French 'parfournir', meaning 'to accomplish'.

Initially, 'randomly' meant 'impetuous rush', but over time it evolved into its current meaning of 'without a specific plan or pattern'.
