(See) Suppose events A_n satisfy P(A_n) \rightarrow 0 and ∑_n=1^∞ P(A_n^c ∩ A_n+1) Prove that P(A_n \text occurs infinitely often
Question: Suppose events \(A_{n}\) satisfy \(P\left(A_{n}\right) \rightarrow 0\) and
\[\sum_{n=1}^{\infty} P\left(A_{n}^{c} \cap A_{n+1}\right)<\infty\]Prove that
\[P\left(A_{n} \text { occurs infinitely often }\right)=0\]
