Final answer:
A total of 13 people died in the incident; initially 10 smokejumpers and the forest fire guard perished, and subsequently 2 smokejumpers died from severe burns.
Step-by-step explanation:
The question asks us to determine the total number of deaths from a given scenario involving smokejumpers and a forest fire guard. Initially, 10 smokejumpers and the forest fire guard perished, which adds up to 11 people (10+1). After that, 2 smokejumpers later died from severe burn wounds. To find the total number of deaths, we simply add the numbers together.
Starting with the original 11, we add the 2 additional deaths, leading to a total of:
11 (initial deaths) + 2 (later deaths) = 13 deaths.
This calculation concludes that a total of 13 people died as a result of the incident involving smokejumpers and the forest fire guard.
