Assume that Maria Petrovna has `x` liters and Olga Pavlovna has `y` liters of jam left. The numbers \( x \) and \( y \) are randomly and independently chosen from the interval from 0 to 1. A random point with coordinates \( (x, y) \) is chosen from the unit square \( F \). When Maria Petrovna ate half of her remaining jam, she had \( \frac{x}{2} \) liters of jam left. Therefore, the event \( A \) “Maria Petrovna and Olga Pavlovna together have no less than 1 liter” is represented by the inequality \( \frac{x}{2} + y \geq 1 \) and graphically depicted as a triangle above the line \( y = 1 - \frac{x}{2} \). Then

\[ \mathrm{P}(A) = \frac{S_{A}}{S_{F}} = \frac{1}{4} = 0.25 \]
