Question 3: Consider the contingency table from Question 2.
Post-flight respiratory problem? Yes
No
Re-circulate Air (RA) 110
405
Do not re-circulate air (RAc) 108
477
A passenger just gets of a flight from San Francisco to Denver. What is the probability
-
(a) What is the probability that they flew on (i) on a plane that re-circulated the air? (ii) will have post-flight respiratory problems?
-
(b) he/she will have flown on a plane with re-circulated air or will experience post-flight respiratory prob- lems?
-
(c) If he/she experienced post-flight respiratory problems, what is the probability they flew on a plane where the air was not re-circulated?
-
(d) Are the events ‘RA’ and experiencing ‘post-flight respiratory problems mutually exclusive events? Independent events?

2) Consider a frictionless horizontal air hockey table. A red
disk of mass M and speed 4V travels in the +y direction. It
collides elastically with a blue disk at rest. After the collision,
the red disk is moving in the -x direction at speed 3V. Find the
mass of the blue disk as a function of M.
