Answer:
a) 0.998856
b) 0.997713
c) 0.999120
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Male death rate
114.4 per 100,000 population
So the survival rate is:
(100000 - 114.4)/(100,000) = 0.998856
Female death rate
44.0 per 100,000 population
So the survival rate is
(100000 - 44)/(100,000) = 0.99956
a) If a male in that bracket are randomly selected, what is the probability that he will survive? ( Express the answer with six decimal places.)
The survival rate for males is of 0.998856. So this is the probability that he will survive.
b) If two males in that ages bracket are randomly selected, what is the probability that they both survive?
Each one has a 0.998856 probability of surviving. So
c) If two females in that age bracket are randomly selected, what is the probability that they both survive?
Each female has a 0.99956 probability of surviving. So
