This week in school, there is a 75 percent probability of having a fire drill, a 50 percent probability of a tornado drill,
and a 25 percent probability of having both drills. Let event F be a fire drill and event T be a tornado drill. Are the two
events independent?

No, because P(F ∩ T) ≠ P(F) • P(T)

Hope it helps!
