full answer please

The probability density function of the age of the babies, x years, being brought to the
clinic to get tested for Covid-19 disease is given by
x(2 – x)
0 <x < 2
f(x) =
otherwise
If 60 babies are brought on a particular day,
i.
Determine how many are expected to be under 8 and 6 months old and
complete the sketch of the probability density function given.
ii.
Express the cumulative distribution function F(x).
iii.
Find the mean age of babies being brought to the clinic.
iv.
Solve for the variance of x and standard deviation for the babies' distribution.
