b) If the software had 5 failures in 100 tests during 10 days of testing, what would be a good estimate of the reliability of the software over the next day? Over the next 5 Week?
c) Draw the control flow graph and determine the McCabes cyclomatic complexity for the following code also mark the node numbers in the code:
cin a b c;
if (a > 10)
{ cout "hello"; if (b < a)
{
cout "part 1"; if (c > a)
{ cout part 2";
