You can put this solution on YOUR website! Of 100 employees of a store located in downtown Boston, 36 people take the subway to work, 24 take the bus, and 14 people take both the subway and the bus.
Draw a Venn Diagram with 2 intersecting circles inside a rectangle.
Label the rectangle "100"
Put "14" in the intersection of the 2 circles
----
How many employees
(a) Take the subway or the bus to work?:: 36+24-14 = 46
------------------------------------------
(b) Take only the bus to work?:: 24-14 = 10
------------------------
(c) Take either the bus or the subway to work (but not both)?
24-14 + 36-14 = 10+22 = 32
-----------------------------------
(d) Get to work by some other means?:: 100 - {10+14+22] = 54
========================
