I'm trying to solve the probability question below;

gas station has $ 5 $ filling points $ 3 $ are used to fill gasoline and remaining $ 2 $ are used to fill the diesel for different types of vehicles.It has been noticed that a $ 3 $ minutes to refuel in any vehicle (diesel / gasoline). The number of gasoline vehicles entering the service station within the estimated time is: $ 24 $ and the diesel vehicle estimated at 36 in the hour.

want to find below the probabilities:

  1. all fuel points are at rest
  2. all diesel refueling points are occupied
  3. all the filling points of gasoline are occupied
  4. all filling points are occupied
