The purpose of this research is to study the level of probability literacy of Grade 11 students of Sanpatong Wittayakom school who studied with real-life situations.

The target group is the students from Mathayomsuksa 5 room 1 of Sanpatong Wittayakom school, Sanpatong district. The research instruments consist of the lesson plans of Grade 11 probability using real-life situations, the worksheets, and the 8-item-pre- and post-test of probability literacy for Grade 11 students.

The result shows that after the provision of learning, the majority of students are in level 4 in all 6 constructs of probability literacy in which the percentage increases of students who have the probability literacy in level 4 from the pre-study phase in each construct are as follows: sample space 16.67%, experimental probability of an event 96.67%, theoretical probability 56.67%, probability of the union of events 36.67%, probability of the mutually exclusive events 20.00%, probability of the difference of events 10.00%, probability of the complement of the events 33.33%, comparing probability 26.67%, conditional probability 30.00%, and independence 40.00%.
