I dont know what the underlined part is saying, or what it is asking

1. The problem statement, all variables and given/known data

For n >= 1, let X1,X2, . . . ,Xn denote n independent and identically distributed random variables

according to X, with cdf FX(y). Let Y = max{X1,X2, . . . ,Xn}.

Show that the cdf FY (y) of Y

satisfies

FY (y) = (FX(y))^n .................y in the set R.

2. Relevant equations

none

3. The attempt at a solution

I think Y = max{X1,X2, . . . ,Xn} means the maximum discrete random variable in that set. And Y takes the maximum value.

Does this mean Y represents only 1 single discrete random variable from this set: {X1,X2, . . . ,Xn}.

Am i correct?????
