 Venn diagrams (optional)
This module introduces Venn diagrams as a method for solving some probability problems. This module is included in the Elementary Statistics textbook/collection as an optional lesson.
A
Venn diagram is a picture that represents the outcomes of an experiment. It generally consists of a box that represents the sample space S together with circles or ovals. The circles or ovals represent events.
Suppose an experiment has the outcomes 1, 2, 3, ... , 12 where each outcome has an equal chance of occurring. Let event
$A=\text{{1, 2, 3, 4, 5, 6}}$ and event
$B=\text{{6, 7, 8, 9}}$ . Then
$\mathrm{AANDB}=\text{{6}}$ and
$\mathrm{AORB}=\text{{1, 2, 3, 4, 5, 6, 7, 8, 9}}$ . The Venn diagram is as follows:

Flip 2 fair coins. Let
$A$ = tails on the first coin. Let
$B$ = tails on the second coin. Then
$A=\{\mathrm{TT},\mathrm{TH}\}$ and
$B=\{\mathrm{TT},\mathrm{HT}\}$ .
Therefore,
$\text{A AND B}=\left\{\mathrm{TT}\right\}$ .
$\text{A OR B}=\{\mathrm{TH},\mathrm{TT},\mathrm{HT}\}$ .
The sample space when you flip two fair coins is
$S=\{\mathrm{HH},\mathrm{HT},\mathrm{TH},\mathrm{TT}\}$ . The outcome
$\mathrm{HH}$ is in neither
$A$ nor
$B$ . The Venn diagram is as follows:

Forty percent of the students at a local college belong to a club and
50% work part time.
Five percent of the students work part time and belong to a club. Draw a Venn diagram showing the relationships. Let
$C$ = student belongs to a club and
$\mathrm{PT}$ = student works part time.
If a student is selected at random find

what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
learn
no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts

what is variations in raman spectra for nanomaterials
ya I also want to know the raman spectra
Bhagvanji
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
Nasa has use it in the 60's, copper as water purification in the moon travel.

is there industrial application of fullrenes.
What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
