They will move backward at a lower speed than the basketball moves forward.
The principle of conservation of linear momentum states that the sum of the initial momentum is equal to sum of final momentum.
Initial momentum = Final momentum
The forward momentum of the basketball = Backward momentum of the person and the chair
Since the mass of the person and the chair is greater than the mass of the basketball, the person and the rolling chair will move backward at a lower speed than the basketball moves forward.
