Ever since I was small I've wanted to do something with Animals. Earlier on I wanted to be a vet, and then a marine biologist, but I really think I've discovered my true calling. I want to be a Zoologist, speciallizing in big cats, Lions especially.

Can any of you please help me in deciding how I should prepare for this career? I'm still in school right now but are there any special classes I need to take, or schools I need to go to in order to achieve this goal? I just don't want to have this dream job in my head, and then get to college only to discover how ill prepared I am...

ok i don't know how to do any part of my science fair! it is way to confusing! my question is:::: After consuming caffenie how does the pulse and body temperture vary from child to adult? OK i need to know what the Independant variable is, how to mesure it and the units of measurments. Then I need the Dependant variable i neeed to know what the dependant variable is , how to mesaure it, and the units of mesurments? Then i need the science concept your project deals with? Please someone help me, this is only my 2nd time doing it and the first time i got a bad grade on it! Ok after that if you can give me a couple of book names or websites i can visit to get information on this project, that will be much appresiated...THANK YOU!!

Can someone please explain step by step how to calculate the probability that 3 siblings would each have their "Golden Birthday" in the same year?

"Golden Birthday"= The year in which you turn "X" years old if your birthday is the "Xth" day of any given month. (My birthday is Feb 4th 1980 so my "golden birthday" year was 1984, when I turned 4. If your birthday is the 15th of the month, it would be whatever year you turned 15, so on & so forth. . . )

Here are the facts:

Oldest was born the 24th of September,
Middle was born the 21st of October,
Youngest was born the 16th of December

AND ALL IN THE SAME YEAR:
Oldest turned 24yrs old,
Middle turned 21yrs old, AND
Youngest turned 16yrs old.

What is the statistical likelihood of this happening in any given family in any given year? What are the odds of this happening when 3 siblings are involved?
