Question: 1) You need to write an "averageThree" function to return the average of three integers. averageThree :: Integer -> Integer -> Integer -> Float

2) You need to write a "howManyAboveAverage" function which returns how many of three integer inputs are above its average value. (utilize the averageThree function.) howManyAboveAverage :: Integer -> Integer -> Integer -> Integer

3) You need to write a "howManyWithinThreshold" function that returns how many of the first three argumentsare within the threshold (the fourth argument) of the average of the first three arguments. (utilize the averageThree function and the logic in the howManyAboveAverage function.) howManyWithinThreshold :: Integer -> Integer -> Integer -> Float -> Integer

I personally have completed (1), which is: averageThree :: Integer -> Integer -> Integer -> Float averageThree a b c = (fromIntegral (a + b + c)) / 3

All i need is help with 2 and 3 where i am stuck!
