Geometry & Continuous Random Variable Distribution

Consider the following probability distribution of a continuous random variable X that is symmetric around zero:


PLEASE SEE ATTACHED JPEG

a. Find the value of a, which is the value f(y) when y = 0.
b. Find the value of b such that Prob(Y>b) = 0.05.
c. Given your answer b to part (b), find Prob (|Y| > b)

I'm sure this is pretty basic and I'm not so much looking for an answer as I am looking to learn how to understand this

Thanks

Re: Geometry & Continuous Random Variable Distribution

update
I may have solved for a.
1/2 (3 x A) = .5
A = 1/3

y/n?
