In this video, we explore how to calculate probabilities by analyzing a list of data. We'll work through several examples using a sample list of student details (age and city). We'll calculate the probability of events involving 'OR' and 'AND' conditions, such as a student being older than a certain age OR living in a specific city, or a student's age being a prime number AND them not living in certain cities.
