It requires analyzing the probabilities of two Earth-like planets transiting based on their orbital periods and the properties of their host stars. Given that Planet_1 has a shorter orbital period and is hosted by a more massive star, the task is to determine which planet has a higher probability of transiting, guiding researchers in their observational choices. The goal is to select the planet that maximizes the likelihood of observing a transit."}
