How do we find the Probability? The probability, P. of an event is the ratio of successful outcomes, called
successes to all outcomes of the event, called possibilites

Probabilities can be written as
and
Example 1:
You are carrying 6 folders in your backpack. Your best friend ask

answer:

c 60% on edg

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

hope this you
