Your question is Ensemble Majority Vote Accuracy. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Give 3 distinct binary classifiers that each achieve 80% accuracy on the same task; what will be the accuracy of an ensemble using majority vote?
Assume the classifiers make independent errors and predict the same binary label. State the ensemble accuracy and briefly justify it. No code is needed, but be explicit about the probability calculation and any assumptions.
