Expected returns: You have chosen biology as your college major because you would like to be a medical doctor. However, you find that the probability of being accepted to medical school is about 10...


So expected returns are just a little more advanced version of probability - without getting too in detail it uses weighted averages so you do not have to add the same number 17 times.
Let's first define our variables:
E(X) = Expected Return X1 = Variable 1 P1 = Probability 1 (in decimal format so 55% would be .55) X2 = Variable 2 P2 = Probability 2 (P2 is also equal to 1 - P1)
So the expected return formula is as follows:
E(X) = (X1)*(P1) + (X2)*(P2)
Plugging in our given numbers we get E(X) = Expected Return X1 = 300,000 P1 = 10% or .1 X2 = 40,000 P2 = 1 - P1 = 1 - .1 = .9
E(X) = (300,000)*(.1) + (40,000)*(.9) E(X) = 66,000
Now remember this does not include the opportunity cost of spending your four years in college studying biology instead of another degree.

I was exploring the APPS key, ended up at the coin toss, and cannot figure out how to exit, turn off, etc. HELP!


  1. Press [Y=] (Esc) meaning Escape to return to menu.
  2. But before, the calculator will ask you whether you want to clear all trials from memory.
  3. Answer [Y=] (Yes). You will be returned to the Probability Simulation List of simulations.
  4. Press [GRAPH](Quit).
  5. You will be prompted again if you want to quit.
  6. Answer [Y=] (Yes).
You might want to explore the RAM to see if the ProbSim App is still stuck in memory. I do not think it will stay loaded, but third-party programs or apps usually remain in memory, and sometimes prevent you from using the calculator the normal way.

My 1-var stats button is not working it says the


Hi,
You will have to report faithfully the message returned, you cannot use your interpretation of the message. Error messages are codified. Each one will correspond to very particular error conditions. I did check the manual for all possible error messages and there is none that states wrong info.

My hunch is that there are errors in your data, but I can't say what type of error: I do not have the actual message returned. Verify you data, item by item, and try again.

To make sure that the calculator is well configured to do statistics
  1. Press [STAT][5:SetUpEditor][ENTER]
  2. Press [2nd][0] (CATALOG) and press [PRGM] (C) to jump to the first command starting with C.
  3. Scroll down to [ClrAllListsts] and press [ENTER]
  4. Calculator replies Done
Restart your statistical data entry.

Hope it helps.
Thank you for rating this solution

When clicking on graph button screen shows invalid dim How do i fix this?


Your poor calculator just can't seem to fit the values you want onto your graph without risking unsightly stretch marks. To fix this, either press the "ZOOM" key and return to "ZStandard", or press "WINDOW" and define more acceptable (or possible) dimentions.

Hi there, there are a couple possibilities. First, Remove the cover where the paper feeds out, if there is a ribbon or an ink roller in there it will need replacing. This you can get a staples. The other possibility is, if there is no ribbon or ink roll, it is probably a thermal printer which means is uses a special heat sensitive paper. If this started when you changed the paper, this is most likely the problem. This you can also get at staples!
