This Streamlit app project, designed as an interactive Lottery Probability Calculator, bridges the gap between statistical analysis and user engagement through an intuitive web interface. Users can input a set of six unique numbers (1 to 49) and select their desired count of winning numbers (2 to 5) to calculate the probability of matching in a 6/49 lottery format. Leveraging historical lottery draw data, the app not only computes the odds of winning but also illustrates how often the selected numbers have historically matched, providing a practical context to the probability calculations.

The application employs a combination of combinatorial mathematics and data visualization to deliver insightful analyses. It features an algorithm that processes all possible combinations of chosen numbers against historical outcomes, displaying the results through an interactive Plotly bar chart. This chart showcases the frequency of partial matches, making the statistical information accessible and engaging.
