Answer:
A. P(success/age≥60) = 12.5%
B. Yes, the success is independent of age.
Step-by-step explanation:
Probability of success, given that a climber is at least 60 years old is calculated using conditional probability rule
P(A|B) = P(A n B)/P(B)
Probability of success given that a climber is at least 60 years old is given by
P(success|age≥60) = P(success n age ≥ 60)/P(age ≥ 60) = 0.005/0.04
= 0.125
P(success|age≥60) = 12.5%
B. The success is independent on age
