Changing the goal posts I see. We were talking about cadaver dog accuracy. In your example there is only one case were both dogs are wrong I.e. 1/25 =4%.
In multiple tests for cadaver the more tests are made the less likely are the alerts to be incorrect.
The above is amended from a statistics text demonstrating why uncertainty in drug trials decreases rather than increases if the final outcome is determined by two separate tests which are unconnected and different in kind.
The matrix above demonstrates every possible outcome for two dogs, one cadaver/blood, one blood alone, reacting to the possible of presence of cadaver- exactly what we are arguing about. In twenty five possible results, sixteen are correct and nine are wrong, meaning that sixteen out of twenty five are right which is 64%.
Please supply your reasoning in a similar way to demonstrate that the certainty increases rather than decreases.
If you cannot we shall just have to assume you have forgotten the statistical ability you claim to have had once.
No simple denial please- rational argument with mathematical rigidity.
