Prove the indicator function
The collection of sets {A} for which A₁ = [i,i+1) form a partition of [0,00)
An indicator function of the set A is the function on given by
if w€ A
if w€ A
Operations on indicator functions are equivalent to set
1₁(w) =
(1
so that 14 indicates whether A occurs.
operations on events
1AUB= max(1A, 1B}
1AOB = min{14, 18} = 1A1B
1AC=1-1A
1AAB = 11A 1B|
