An automated greenhouse ventilation system is programmed to activate an extraction fan (FFF) if and only if the carbon dioxide levels are critically high (CCC) AND at least one of two other conditions is met: either the ambient temperature is too high (TTT) OR the relative humidity is too high (HHH).
An intern wrote down the following incorrect Boolean expression for this control system:
F=C+(T⋅H) F = C + (T \cdot H) F=C+(T⋅H)Choose the option that shows the correct algebraic expression for the extraction fan.
F=(C⋅T)+HF = (C \cdot T) + HF=(C⋅T)+H
F=C⋅T⋅HF = C \cdot T \cdot HF=C⋅T⋅H
F=C⋅(T+H)F = C \cdot (T + H)F=C⋅(T+H)
F=(C+T)⋅HF = (C + T) \cdot HF=(C+T)⋅H
