The video tutorial introduces geometric probability, starting with a rectangular field example where the probability of finding a lost ring is calculated by comparing the area of a smaller rectangle to the total field area. The tutorial then moves to a more complex example involving an outer ring, where the probability is determined by calculating the areas of a square and a circle. The video emphasizes understanding probability through geometric scenarios and area calculations.
