Researchers at the Louisiana State University Center for Energy Studies gathered data on both active and inactive oil and gas structures in the Gulf of Mexico. They discovered that the gulf had 2175 active and 1227 inactive structures at the end of 2003. The following table breaks down these structures by type (caisson, well protector, or fixed platform).
Caisson Well Protector Fixed Platform Totals
Active 503 225 1447 2175
Inactive 598 177 450 1225
a. List the simple events for this experiment.
b. Assign reasonable probabilities to the simple events.
c. Find the probability that the structure is active.
d. Find the probability that the structure is a well protector.
e. Find the probability that the structure is an active caisson.
f. Find the probability that the structure is either inactive or a fixed platform.
g. Find the probability that the structure is not a caisson.
