An office and apartment building is made up of modules. Each module is a rectangular

prism. The building has 130 modules, and is 13 stories high.

If all of the modules were divided evenly among the number of stories, how many modules

would be on each floor?

How many different rectangular prisms could be made from that number?

If all of the modules were divided evenly there would be 10

modules on each floor.

different rectangular prisms could be made from the number of modules on each

The probability that a u. s. resident has traveled to canada is 0.18 and to mexico is 0.09. a. if traveling to canada and traveling to mexico are independent events, what is the probability that a randomly-selected person has traveled to both? (page 109 in the book may ) b. it turns out that only 4% of u. s. residents have traveled to both countries. comparing this with your answer to part a, are the events independent? explain why or why not. (page 119 may ) c. using the %’s given, make a venn diagram to display this information. (don’t use your answer to part a.) d. using the conditional probability formula (page 114 in the book) and the %’s given, find the probability that a randomly-selected person has traveled to canada, if we know they have traveled to mexico.
