Please help me to answer these questions for cumulative distribution of the random variable X

The cumulative distribution of the random variable X is given by
G(x) = 0                    for x<0
           3x2-2x3          for 0≤x<1
           1                   for x ≥1

a)Find the probability density function g(x).
b)Use the cumulative distribution G(x)to compute P(X < ¼) and P(X> ½)
c)Find the mean of the random variable x.
d)Find the standard deviation of the random variable
