Two events A and B are chosen such that Pr(A given B) is equal to 1/3 and Pr(B given A) is equal to 1/4. Pr(A and B) is also equal to Pr(Not A and Not B).

From this, find Pr(A), Pr(B) and Pr(A or B).

so what is the question

step-by-step explanation:

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
