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
Answer:
A , B, C, E
Step-by-step explanation:
√4 = 2
√5 = 2.24
√5.5 = 2.36
√6 = 2.45
√8 = 2.83
√9 = 3
<h3>A)</h3>
√5 < 2.3<√6
2.24 < 2.3 < 2.45 True
<h3>B)</h3>
√5 < 2.4<√6
2.24 < 2.4 < 2.45 True
<h3>
C)</h3>
√4 < √5 < √5.5
2 < 2.24 < 2.36 True
<h3>D)</h3>
√8 < 3 < √9
2.83 < 3 < 3 False
<h3>E)</h3>
√8 < 2.9 < √9
2.83 < 2.9 < 3 True
<h3>F)</h3>
√4 < 4.5 < √5
2 < 4.5 < 2.24 False
The first one will get 10$
