Homework Statement
If X1, X2, X3, ... Xk are independent events, prove that
P(X1 U X2 U X3 U ... U Xk) = 1 - [1 - P(X1)][1-P(X2)]...[1-P(Xk)]

The Attempt at a Solution
Well I have tried a few methods, but I know it's got something to do with
P(X1) = cc(P(X1)) (complment complement)
P(X1) = 1 - c(P(X1))
P(X1) = 1 - (1-P(X1))
I know that much, but I can't link it in with unions of independent events?? I
