Thanks for the reply! :)
I will try to take this in to consideration while trying to solve it, but I am not all sure what to do...
My problems are duo till tomorrow, I'm hoping I will get them right by then :)
I am new here on the forum and find it a bit difficult to learn the way to go at different statistics/probability - problems.
For the most times I am able to figure it out myself doing some research, but the last two problems has got me stuck for a few days.
I would be really thankful for...
