If I cut my own hair in lockdown last weekend, what is the probability I currently look like someone who isn't allowed within 50m of a playground?

In the red hair question, the probability of chosing a person with red hair is 0.02. Since the probabilty that the next person chosen is red-headed always remains 0.02, does that not mean over two consecutive picks, P(at least one ranga) = 0.02 + 0.02 = 0.04?
