Als would agree to 60%. 3/5 statements are hit. The decisions are not in play, since its decision testing. The boarding pass statement I excluded since is it not derived from a single statement.

Coverage is measured as the number of decision outcomes exercised by the tests divided by the total number of decision outcomes in the test object, normally expressed as a percentage.

Sorry, I was wrong here is the solution: TC1: 1,2,4,5 TC2: 1,6,7,5 TC3: 1,6,8,10 There is total of 10 statements and 8 of them are used. Therefore 8/10= %80

Thanks for your coments. Here is some confused TC content and at the beginning I was counting 7 and not 8 involved statements. After your numbered TC list everything is clear. Here is my diagram with explanations: https://prnt.sc/K6U2emWLrZyu
