What is the reliability of the module if the probability of success is 0.95 during testing? 0.665 to 0.95 At the most 0.665 At the most 0.95 At least 0.665 IS&Software Engineering isro2014 is&software-engineering software-testing + – sh!va asked Jun 7, 2016 retagged Nov 13, 2017 by Arjun sh!va 4.7k views answer comment Share Follow See all 0 reply Please log in or register to add a comment.
5 votes 5 votes Unit testing of the module is covering 70% of the code = 0.7 Probability of success = 0.95 Reliability = 0.7 * 0.95 = 0.665. Answer is at the most 0.665. Please correct me if i am wrong naga praveen answered Jun 12, 2016 naga praveen comment Share Follow See all 7 Comments See all 7 7 Comments reply Aryan commented Jun 27, 2016 reply Follow Share should be aleast. 2 votes 2 votes Rajsree commented Jul 2, 2016 reply Follow Share I think option D is the right answer. Please do tell the correct answer 0 votes 0 votes Sanjay Sharma commented Mar 27, 2017 reply Follow Share if only 70% code is tested then with 95% probability of success then its reliability is at most it is 0.7x.95 =.665 it can not be at least .665 because then it can also be 1 which is not possible without testing rest 30 % and that too with prob of success 1 5 votes 5 votes tryhard commented May 7, 2017 reply Follow Share @sanjay sharma may be i m wrong bt i m having doubt like for 70% its having probablity 0.95 that means 0.70*0.95=0.665 and for remaining part means 30 % it can be have succuss probability 1 (in worst case) means 30% of module part completely reliable. so overall reliable is 0.665+0.30=> 0.965 means if option is like 0.665 to 0.965 is it correct ?? plz verify 3 votes 3 votes sushmita commented Oct 5, 2017 reply Follow Share thanx 0 votes 0 votes Rahul Garg commented Oct 7, 2017 reply Follow Share Right bro.. according to me .. Ans A is more correct. 0 votes 0 votes Sanjay Sharma commented Jan 3, 2020 reply Follow Share what if most (or all errors ) are from that 30 % code which is untested.Then it can not even 0.1 so 0.665 is not guaranteed it is max we can claim And even if 30 % does not contain error without testing that code we can not say it is reliable 0 votes 0 votes Please log in or register to add a comment.

Maximum reliability on 70% code would be=0.7*0.95(as prob. of success given)=0.665 Suppose if we consider it only 60% code under testing then it would be=0.6*0.95<0.665 so At the most 0.665. 0 votes 0 votes Please log in or register to add a comment.
