Risk is an impending or unexpected injury or loss to an individual or business. Reward is a payment or even gift given to an individual for achieving a goal or given for recognition for the efforts made. These two do have a relationship as individuals or businesses do take risks when making any decision as they cannot guarantee that the decision made would allow them to be successful but however people do take risks thinking that they will be successful and rewarded in the future and therefore we say reward and risk go hand in hand.
