The video tutorial covers two main problems. The first problem involves calculating the probability of drawing a card with a number less than four from a shuffled set of eight cards. The solution involves identifying the favorable outcomes and dividing by the total number of outcomes, resulting in a probability of 3/8. The second problem involves analyzing a pie chart to determine the most borrowed book categories in a library. The analysis includes comparing percentages of different categories to verify statements about the data, ultimately identifying the correct statement about the borrowing patterns.
