Maria bought $$4$$ black and a certain number of red and blue pencils at $$15$$ cents each and carried them home in one bag. After Maria came home, she took out one pencil at random to write a note and then put the pencil back into the bag. Sometime later, she needed to write another note and again took out a pencil from the bag. If the probability that Maria wrote both her notes in black is $$\dfrac1{36},$$ how much did she spend on all pencils?

A. $$\3$$
B. $$\3.2$$
C. $$\3.4$$
D. $$\3.6$$
E. $$\3.8$$
