WebThe event “there is at least one false rejection among all m tests” can be written as ∪mj = 1Aj. Using the complementary event and the independence assumption, we get P( m ⋃ j = 1Aj) = 1 − P( m ⋂ j = 1Acj) = 1 − m ∏ j = 1 P(Acj) = 1 − (1 − α)m. Even for a small value of α, this is close to 1 if m is large.
