## Goal
It is your job to predict for each visitor session, **whether it will result in addedToCart (1) or not (0). Your predictions should be a probability between 0 and 1.0**.

## Metric
Submissions are evaluated on [AUC](https://developers.google.com/machine-learning/crash-course/classification/roc-and-auc), which is a number between 0 and 1, where 0 means 100% of the predictions are wrong and 1 means 100% of the predictions are correct. Randomly guessing should give a score of 0.5.

## Submission File Format
The file should contain a header and have the following format:
```
sessionId,addedToCart
121212121212,0.30
3434343434,1.0
...
```
You can download an example submission file (csv) on the [Data page](../data).
