Lower the threshold

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.

Calls are cheap, missing a buyer is not. Flag a user as a likely buyer when the probability of paying is 0.3 or more (not 0.5). Store how many test users get flagged in result.
