SOLUTION: Prove If {B（k) ,k= 1,2, ……,n } is a set of events such that n ∑P[B(k)] k=1 Then n P(∩B(K))＞0 k=1 (Where B（k) is expressed as k is the subscript of B

Question 1163644: Prove

n
∑P[B(k)]
k=1
Then
n
P(∩B(K))＞0
k=1
(Where B（k) is expressed as k is the subscript of B)

.

There is an error in your post, as it is worded, printed, posted and presented.

The error is that the condition " if " describing propery of events B(k), is interrupted and uncompleted.

Twice and thrice check with your source.

Then re-check and cross-check.
