What is the probability that a worker does not lose an arm?
What is the probability that worker does not lose and arm or leg?

Pr(NOT arm)=.98
Pr(NOT arm NOR leg)= 1-Pr(leg)-pr(arm)
Pr(NOT arm NOR leg)= 1-Pr(leg)-pr(arm)

oops.
Pr(NOT arm NOR leg)=1-Pr(arm or leg)
= 1-Pr(arm)-Pr(leg)+pr(arm AND leg)
= 1-.02-.03+.02*.03
Pr(NOT arm NOR leg)=1-Pr(arm or leg)
= 1-Pr(arm)-Pr(leg)+pr(arm AND leg)
= 1-.02-.03+.02*.03
