Question

if y=3,125,000e^-0.23x measures the likelihood of an elderly person surviving a fall at home (x is years, y is probability of survival). find the chance that a 70 year old survives a fall at home?

Answer 1

According to given formula, the probability of surviving a fall of a 70 year old is $y(70) = 3,125,000 \cdot e^{-0.23 \cdot 70} \approx 0.32$.
