Consider the following training data consisting of three features X, X and x3 and the class attribute Y that I could be Red, White, or Black.

Write the expression for the logistic regression function for each of the given binary classification problems 2. Given a new data point (7.7.7), what would you classify it using the One-versus-All (OVA) algorithm? Explain.
