Let's use the formulae we've proved to solve a problem on Probability. We rely heavily on formulae to solve problems discussed in this video. However, we do give a visual intuition of Demorgan's law (as much as is required). These problems help build our muscle of leveraging formulae to simplify the expressions given in relatively tougher probability problems. Courses on Khan Academy are always 100% free.
