a. $0.198$ b. $0.188$ c. $0.498$
Sum up all rows and columns. Total =623 a. Given that the death was after 2000, what is the probability that it occurred under a tree? total death after 2000 = 388, $p=(35+42)/388=0.198$ b. Find the probability that the death was from camping or being outside and was before 2001. $p=117/623=0.188$ c. Find the probability that the death was from camping or being outside given that it was before 2001. total death before 2001=235, $p=117/235=0.498$
