A programmer has been asked to create a module RollDice() to simulate multiple rolls of a dice. This module will be used as part of a program for a game. The module will: step 1 - take a positive integer parameter representing the number of times the dice will be rolled step 2 - simulate one roll of the dice by generating a random integer between 1 and 6 inclusive step 3 - output the integer generated step 4 - repeat, as required from step 2 step 5 - calculate the average value of the random integers generated step 6 - return the average value. Write pseudocode for the module RollDice()

Mark scheme

Marking points from the official mark scheme (May/June 2025). The mark or mark type is shown in brackets.

1. [7] Example solution: FUNCTION RollDice(NoOfTimes : INTEGER) RETURNS REAL DECLARE RollValue : INTEGER DECLARE Average : REAL DECLARE Count : INTEGER DECLARE Sum : INTEGER Sum <- 0 FOR Count <- 1 TO NoOfTimes RollValue <- INT(RAND(6)) + 1 OUTPUT RollValue Sum <- Sum + RollValue NEXT Count Average <- Sum / NoOfTimes RETURN Average ENDFUNCTION
2. MP1 Declare all variables used and initialise Sum to 0
3. MP2 Loop for 'number of times' parameter
4. MP3 Use RAND() function with Integer parameter in a loop
5. MP4 Use INT() function in a loop
6. MP5 Generate a random integer between 1 and 6 in a loop
7. MP6 Output each value generated in a loop
8. MP7 Calculate Sum and if Average used check declared as REAL and return Average and check function header returns REAL
