You just need to multiply both percentages together :) convert them to decimal form and multiply, then convert the answer back to a percentage

P(Get Stuck And Require A Tow car ) = P(x)
$$\large\rm P(x) = Probability~of~Getting~ Stuck * Probability~of~Tow~Car~Used  $$$$\large\rm P(x) = 0.7 * 0.9$$
