I need the answers in the form of a venn diagram.

1.  Draw a Venn diagram showing that all cell phones are communication devices.

2.  Draw a Venn diagram showing males, females, and those who ride bicycles.

Hello Stu_My801,

1.  To show that all cell phones are communications devices, you need
two circles. The outer one is labeled "Communication devices" and the
inner one is labeled "Cell phones". The inner circle is entirely
within the outer circle. Something like this...

  +---------------+
  | Communication |
  |   Devices     |
  |  +----------+ |
  |  | Cell     | |
  |  | Phones   | |
  |  +----------+ |
  +---------------+

2. To show males, females, and those who ride bicycles, you need three
regions that look roughly like this:

  Males    |   Females
           |
   +--------------+
   | Ride         |
   | Bicycles     |
   +--------------+
           |
           |
Where the "Ride Bicycles" circle crosses into both the areas of males
and females (showing both males & females ride bicycles). The line
between males / females should go through the "Ride Bicycles" circle
(but I can't clearly show it in this answer). Note that this diagram
shows there are no males who are females & vice versa.

There are plenty of sites that describe venn diagrams including those
suggested by commenters as well as:
  http://www.nist.gov/dads/HTML/venndiagram.html
which shows several overlapping categories,
  http://www.nova.edu/~hammack/MathDL/Venn/V4.html
which categorizes people as male/female and doctors/not doctors.

or several others accessible with search phrases such as
  male female venn diagram
  venn diagram explanation
  venn diagram illustration
and so on. If you have further questions related to this topic or this
answer is not clear to you, please make a clarification request.

Here are some easy online tools to help you accomplish this task. I
tried the second one but it dosen't let me send you a link to the
outcome.
