To find the probability that at least one product becomes a market leader, it's easier to calculate the probability that neither becomes a market leader and subtract that from 1. The probability that A does not become a market leader is 1 - 0.60 = 0.40, and for B, it's 1 - 0.20 = 0.80. The probability that neither becomes a market leader is 0.40 * 0.80 = 0.32. Therefore, the probability that at least one becomes a market leader is 1 - 0.32 = 0.68.
