A bag with 12 marbles has 5 blue marbles, 3 yellow marbles, and 4 red marbles. A marble is chosen from the bag at random. What is the probability is not blue?

5/12 i think

Step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
