Disjoint but not independent

Post your example of events that are disjoint (no overlap) but not independent (the outcome of the first affects the outcome of the second)

Making cookies!! Cause if you mess up the amount of one ingredient then it messes up the taste of the cookies!!

excellent example. did that once. i had two ingredients - the batter and 1/2cup of water (disjoint). put in 1 cup of water and the batter. my mess up on the first part totally affected the second part(dependent). Yuk!

An example of this would be getting grades in class. It would be disjoint because one grade does not affect the next, but it would be dependent because each grade would count towards the final grade.

If you are putting a computer together and you mess up one of the parts then the whole computer wont work.

I know this isn't the right spot but I have a question for Mrs. Hankes or anyone else who knows. When calculating the standard deviation in the mutual fund combinations (for example, have .8 of Magellan stock and .2 of Japan Stock) in the Special Problem number 7, do you square the percentage (the .8 or .2) and then multiply that by the variance or do you just multiply the .8 or .2 by the variance? Please Help me.
