Explain how to solve this . the answer choices are listed in the image.

Consider the following scenarios where:

Scenario               Probability

NN***                    (.75)⁰(.25)²    =    .0625

rNN**                     (.75)¹(.25)²    =    .0469

rrNN*                     (.75)²(.25)²    =    .0352

rrrNN                     (.75)³(.25)²    =   .0264

                                      TOTAL =    .1710

This didn't produce one of your options, but .1875 is the closest.

ANOTHER WAY TO SOLVE:

(not rained)² x (rained)³ x Abar - # of times the event occurs

= (.25)² x (.75)³ x Abar - 4

The only problem with this method is that I don't know how to find Abar.
