Very low, and for a number of reasons.
If a Pop Tart were to be traveling towards your head, the Pop Tart would have to be going at least 173 mph to break your neck, subsequently being killed. Pop Tarts usually do not travel that fast.
A flying Pop Tart that came directly at any other parts would still result in a very unlikely death, since the rib cage holds the most important organs, and is thus very strong (much stronger than the human neck).
To die from choking on a Pop Tart is also extremely unlikely, because 4,600 deaths occur in the United States out of a population of 307 million people. This is only in the United States; the percentage of choking alone is bigger for the entire world. The 4,600 deaths from choking were also mostly younger kids and infants from small parts, and not from food (which makes it very unlikely for the choking culprit to be a Pop Tart).
Thus, the probability of being killed by a Pop Tart is lower than a calculable percentage due to the vast assortment of things that happen in the world. It is way below 1%.
It is a tart-like pastry, hence the word Tart in its name. The "Pop" does not refer to popping out of the toatser - It was named Pop-Tart as a play on the "Pop-Art" craze at the time of its creation.
