Answer:

(i) probability of next vehicle to leave will be a bus or car  

                         = 0.91

(ii) probability [ next vehicle to leave will be a motorbike]

                    = 0.08

(iii) probability [ next vehicle to leave is not a car] = 1 - probability [ next vehicle to leave is a car]

               = 0.13

Step-by-step explanation:

given, there is parking space for 15 buses, 350 cars and 35 motorbikes

total number of events = 15+ 350+ 35 = 400

P[event]\ =\  \frac{number \ of \ favorable \ outcomes }{total \ number \ of \ outcomes}

(i) probability of next vehicle to leave will be a bus or car  

                      = \frac{15+350}{400}

                      = \frac{365}{400}

                         = \frac{73}{80}

                         = 0.91

(ii) probability [ next vehicle to leave will be a motorbike] = \frac{35}{400}

                    = \frac{7}{80}

                    = 0.08

(iii) probability [ next vehicle to leave is not a car] = 1 - probability [ next vehicle to leave is a car]

                 =  1 -\frac{350}{400}

               = 1- \frac{7}{8}

               = 1-  0.87

               = 0.13
