Question 563808
A Johnson Space Center analysis estimated a 1 in 71 chance of losing the International Space Station to space debris or a meteoroid hit. 
(a) What kind of probability is this? Explain.
-----
It's probably based on the density of space debris and meteors
in the proposed Space Station path and the cross-section of
the Space Station as it flies its orbit.
--------------------------------------------------------- 
(b) What is the probability of losing the station in this way?
Ans: 1/71 = 141/10,000
