help with homework

If you intend asking programmers to compare apples and oranges, it's better do it on the VB forum... ;P Perl combines all the worst aspects of C and Lisp: a billion different sublanguages in one monolithic executable. It combines the power of C with the readability of PostScript. -- Jamie Zawinski
hehehe :-D Ant.

Hi Could you guys check if my homework is correct: Q A box (A) contains 8 apples and 4 oranges Another box (B) containes 10 apples and 2 oranges A fruit is picked from a random box, and found to be an apple. what is the chance of this apple comming from box A. Use Bayes theorem. scroll down for my answer A: 8/12 * 1/2 ---------------------- 8/12 * 1/2 + 10/12 * 1/2 = 0.444

It depends. You have to take into accoun the Heisenburg uncertainty principle. You can know the location of the object, you can known whether it is an apple or an orange, but you can't know both at the same time. :-D Remember, even if you win the rat race, you're still a rat.

Not to mention the possibility that you pick up an apple masquerading as an orange. Those fruit can be wile, you know. BW CP Member Homepages

You're right. I didn't go through and calculate .444 but the equation above it is correct. Out of curiosity how might you calculate this without using Bayes theorem? Saying "use Bayes theorem" is kinda redundant... or at least it is to me as I can't think of another way to approach it.

There is always brute force. Calculate all posibilities and just count apples and oranges. (or boxes in this case.) My goal is to look at code like a chessmaster looks at a chessboard to see positions and possibilites beyond lines and characters.

You cant compare oranges to apples! top secret

In this case they are one in the same since there isn't a bias towards one basket. 8/12 * 1/2 24 ---------------------- * ----- 8/12 * 1/2 + 10/12 * 1/2 24 = 8 --- 18 = .444

Again I am amazed by the power of marketing. :-D

I guess technically we are both wrong since .444 isn't the "right" answer but instead .4444444 with 4 repeating ad infinitum but I can figure out how to put a line above the 4. ;P
