My answer would be c. 26%.
My approach to the solution:
The probability of auto demand rising more than 5% during the coming year is 60%.
Therefore, the probability of auto demand NOT rising more than 5% during the coming year is = (100% - 60%) = 40% = 0.4
The probability that the demand for cable television will rise more than 10% is 35%.
Therefore, the probability that the demand for cable television will NOT rise more than 10% is = (100% - 35%) = 65% = 0.65
The probability that both these independent events will NOT occur = P(auto demand not rising) X P (cable demand not rising) = 0.4 X 0.65 = 0.26 = 26%
