Question: How can I solve float(infinity)? please help me.

Dear All,

I am a bigginer of Maple. I'm trying to solve the following in Maple.


> with(Statistics);
> f := Distribution(NormalDistribution(0.3,1));

> Y := RandomVariable(f);
> fy := PDF(Y, y);

> Fy := CDF(Y, y);

> int((diff(-ln(1-Fy), y))*fy, y = -infinity .. infinity);

> w := evalf(%);


But Maple told me that the answer is the integral -float(∞)..float(∞).

I really need to get a kind of numerical answer. Would it be possible? Please Help me!!
