Assuming that the daily wages for workers in a particular industry averages Birr 11.90 per day and the standard deviation is Birr 0.40. If the wages are assumed to be normally distributed, determine what percentage of workers receive wages between Birr 12.20 and Birr 13.10 less than Birr 11.00 more than Birr 12.9​
