Is it better than guessing?

Use the three inputs videos_watched, quiz_score and days_active, a 0/1 answer paid_flag (1 = paid), and train_test_split with test_size=0.25, random_state=42 and stratify on the answer. Train LogisticRegression(max_iter=1000) on the training part.

A lazy "model" that always says "will not pay" also gets a high accuracy when payers are rare. Store [accuracy of always saying 0 on the test part, the model's test accuracy], each rounded to 3 decimals, in result.
