Ok, so you would add dogs and cats to find the number of ALL pets, 132+18, which equals to 150.
The "probability of a student preferring a dog" means "what are the chances in terms of fraction that student will prefer a dog.

so, 
132/150  (can you simplify this fraction, if no, let me know and I'll help you more...

Also, for a future reference:

you can find any section by:
1)  clicking "more subjects"  ( top left corner, towards the center)
2)  typing in the name of the section (name of a section can be "history" Mathematics and other section for each unique area of studying.

you can fan someone by:
1)  clicking on the user's name
2)  clicking "fan" on the bottom right corner of user's box.
( you can also write a testimonial by clicking "add testimonial" )


you can mention someone in your question (or in any other question)  by writing @ in front of their name, just like I would mention you...  LOOK ! ....  @peterpiper4 (they would get a notification that they got mentioned just like you did)


you can message someone by:
1)  clicking on the someone's username
2)  clicking "Send Message"
3)  type your message press submit, and wait till the messages submits.


If you have any questions you can message me or anyone else on this website. We will be happy to respond !

Not a problem... if you are uncomfortable with something don't hesitate to say it.

I still don't know how to simply the 132/150. and I don't know the B. and C. of the problems

solomonzelman · Answer

well,
$$132=6 \times 22$$$$150=6 \times 25$$So you would divide top and bottom of  132/150  by 6,
and you will get 22/25.
