Explanation / Answer

Solution :

the probability that the randomly choosen death is due cardiovascular disease = 0.39

the probability that the randomly choosen death is due cancer = 0.25

( a )

the probability that the randomly choosen death is due cardiovascular disease or cancer = 0.39 + 0.25

= 0.64

( b )

the probability that the randomly choosen death is due to other disease = 1 - 0.64 = 0.34
