H Everyone,

Can someone please tell me what the following chances of winning is:A customer receives 1 ballet for every \$5,000 they spend with our company during a promotion. There are a total of \$3,000,000 in purchases over the course of the promotion and therefore 600 ballets are handed out. There are a total number of 100 customers entered into this promotion although not all spend the same amount of money, some may spend \$5,000 and receive 1 ballet while others may spend \$50,000 and receive 10 ballets. We will draw 10 ballets at the end of the promotion.

What is the probability of being drawn that each ballet handed out provides?

Thanks!

BG

Hello bradg and welcome to MHB! :D

I've edited your post to provide correct rendering (precede '\$' signs with a backslash) and enhanced the title to be more descriptive of your problem.

We ask that our users show their progress (work thus far or thoughts on how to begin) when posting questions. This way our helpers can see where you are stuck or may be going astray and will be able to post the best help possible without potentially making a suggestion which you have already tried, which would waste your time and that of the helper.

Can you post what you have done so far?
 
I'm not quite sure where to begin.. which is why I posted on the site. Looking for someone to help solve this for me as it is a real life question we need answered.

Thanks!

I believe that the probability would be 10/600 = 1/60, i.e. each ballet has a one in sixty chance of being selected, given a guaranteed random draw.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
I'm interested to know whether the equation $$1 = 2 - \frac{1}{2 - \frac{1}{2 - \cdots}}$$ is true or not. It can be shown easily that if the continued fraction converges, it cannot converge to anything else than 1. It seems that if the continued fraction converges, the convergence is very slow. The apparent slowness of the convergence makes it difficult to estimate the presence of true convergence numerically. At the moment I don't know whether this converges or not.
