you have been told that
continue further to find the cdf of Y....
consider rolling a die.
P(s)=1/6 for all s in S
X= number on die so that X(s)=s for all s in S
compute the cumulative distribution function Fy(y) = P(Y<=y), for all y in the set of real numbers.
for Y=1 i get
Is this all I have to do for Y=1, or do I have to integrate, or is there anything wrong?
