Predict probabilities of movie reviews

In this problem, you will build a logistic regression using the movies dataset. The labels are stored in the arrayy and the features in X.

Train the model on the training data. Instead of predicting classes, predict the probabilities that each instance in the test set belongs to each of the two classes.

The logistic regression and train/test splitting functions have been imported for you.
