You have given the option for the probability of any given human having both the light colored hair and dimples that will be the product of frequency of these two independently occurring events.So the probability that any given individual will have both the events will be product of their respective frequency =0.4 x 0.5 = 0.2 is the answer as per your given options.

It is sure that in case of either or situation the law of addition will come into force. So the probability that any given individual will either have light hair or dimple will be the sum of their respective frequency=0.4 + 0.5=0.9 which is not given in options.Both the answers are correct as per the situation
