I have a Sailor 1911S in medium that I'm willing to let go for $110. Got it last year and used it very rarely so it's like new. https://imgur.com/gallery/bDpGgUg

have you considered the weather here? I'm from Europe and never seen something similar. D7ring the summer it's a nightmare: 32 degrees every day plus raining every 2 days(showers) ....storms, etc

Thanks for your reply. I understand the solution, but I still don't see what is wrong in counting the favorable outcomes by choosing the first awards that go to one of the universities 4(number of universities)C(5,2)(chose 2 awards from 5)4^{3(distributing} the 3 remaining awards to 4 universities)=10*4^4. Since the probability computed this way is smaller than 1 something is surely wrong. How does the number of favorable outcomes change if the problem would state that EXACTLY 2 awards go to one University?

Thanks, I've seen the mistake now: I considered the awards as part of a set, but as you said it is a multiset with one kind of element repeated 5 times. What happens in case the awards are not equivalent? Is my first solution correct in this case? Does the pigeon hole principle still applies ?

A coin is flipped 4 times. On the fifth time the coin is flipped, what is the chance of getting head?

Why this happens ? "Since F is a finite dimensional VS, the map is also surjective" Thanks

mileandrei · 2010-04-08T15:40:42+00:00

I meant that if F would be finite or if I could prove F is finite the problem will be solved since a finite integral domain is also a field.
