A consulting firm submitted a bid for a new research project. The company overseeing the bids regularly requests additional information to help with their assessment and final decision. Historically, 65% of all bids require additional information to be submitted. Past experience also shows that for 85% of the bids which required additional information were successful and 75% of the bids where additional information was not requested were not successful.

Use A to represent the event 'Additional information was requested' and

S to represent the event 'Firm was successful in getting the project'.

Use the correct statistical notation and words to define the complement of both S and A. (Use this terminology in your working throughout the remainder of this question).
