Answer:
71.43% conditional probability that she will survive to 80 years
Step-by-step explanation:
We have these two following events.
Event A:
Living to be 70. So P(A) = 0.7
Event B:
Living to be 80. So P(B) = 0.5
The conditional probability formula is given by:
In which P(B|A) is the probability of B happening given that A has happened and is the probability of both events happening.
(a) If a woman from that country is 70 years old, what is the conditional probability that she will survive to 80 years
If a person lives to be 80, she must have lived to be 70. So
71.43% conditional probability that she will survive to 80 years
The answer is A because in the dotted line it corresponds to “y -3x-3”. You rise 3 and run only 1. The dotted line is going to the left because it’s a negative 3. The “y 1/3x-3” is the rise of 1 and the run of 3. Then place 0 into the x and y. Then once you place the 0 into both problems and if the problem is true then shade where the point 0,0 is. Since this problem is not true when placing 0 into the equation then you don’t shade where 0,0 is. Hopefully I explained this correctly.
