Default Struggling with a problem

There are events A(1),A(2),A(3),....A(N) are independent. Suppose that:

P(A sub k) = 1/(k+1) For 1<=k<=n

Find the probability that none of the n events occur. This seems like an infinant tree of some sort and I am struggling to find a good starting point. Thanks in advance for any help.
