Assuming independence, where the choice of one has no effect on the other,
the probability that neither has a complaint is 0.97*0.97=0.9409.
The probability that one has a complaint is 0.97*0.03*2, since there are two ways one complaint can occur.
That is 0.0291*2=0.0582
Not asked for, but the probability that both have a complaint is 0.03*0.03=0.0009.
Those probabilities add up to 1.0
