#1 please and the answer should be in the form of a piecewise function
1.
The probability density function must be positive between -1 and 1.
Also, since it represents picking a number at random, its value must be the same for all numbers
between -1 and 1, then the function is constant in the interval [-1,1]
Therefore the function is of the form
where k is a constant.
Now, recall that the integral of a PDF over all reals must be equal to 1.
Hence
Then
Thus, the PDF is
