Lani had a box that contained: 1 blue marble 1 green marble 1 purple marble 1 yellow marble 2 red marbles Lani removed one marble without looking and she recorded the result. She placed the marble back in the box and repeated the procedure one more time. What is the probability that she removed a red marble followed by a blue marble?

16.66 and 0.33 im pretty sure

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
