Students answered question 1 and answered question 2 BOTH correctly= 8
Students answered question 1 correctly=18,
Hence , Students answered correctly question 1 DISABLED_event_ONLY= 18-8=10
Students answered question 2 correctly=23
Hence , Students answered correctly question 2 DISABLED_event_ONLY= 23-8=15

Hence Total number of studets=Students answered question 1 and answered question 2 BOTH correctly+Students answered correctly question 1 ONLY+Students answered correctly question 2 ONLY+students answered incorrectly on both questions
Total number of studets=8+10+15+11=44
