Every 15 minutes an express train arrives and waits 4 minutes to pick up passengers. four minutes after the express train leaves, a local train arrives and waits 3 minutes to pick up passengers. if a passenger arrives at the station at a random time during the rush period, find the probability of each of the following.
1. the express train will be waiting at the station.
2. no train will be waiting at the station.

i think that the probability is out of 15, but i have other people telling me it's out of 26. which is right?

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal
