While it is possible for a tiger to attack a panda, it is extremely rare. Here is why:
Separate Habitats
Tigers prefer lowlands and forests, while pandas live in high-altitude bamboo forests. Their ranges rarely overlap.
Different Diets
Tigers are carnivores, while pandas are herbivores that eat mostly bamboo. They do not compete for the same food.
Size and Behavior
Although a large tiger could potentially overpower a panda, the size difference is not as extreme as with other prey. Pandas can also defend themselves. Tigers are solitary hunters, while pandas spend most of their time feeding, so encounters are unlikely.
There are no documented cases of a tiger attacking a panda in the wild. While technically possible, it is extremely improbable.
