<p>haha oh dear, it’s like talking to myself. i also saw a v cute couple on facebook where the girl went to bu and the guy to mit, both '10…and the girl was indian and the guy was white, like me and my bf! odd isnt it?</p>
<p>No. :-). The probability of two such pairs, a priori, is about 1.</p>
<p>what’s the probability of three BU/MIT '10 pairs, then?</p>
<p>Still about 1. You’d have to think the probability of MITers and BUers dating is very low to expect fewer than three pairs.</p>
<p>but dating since before they became MITers and BUers? (high school) :P</p>
<p>Okay, let’s do this. I am curious myself.</p>
<p>Suppose reasonably smart people date other reasonably smart people. These people choose from – let us say roughly – 100 colleges. I hope you will agree both assumptions are roughly reasonable.</p>
<p>For the first-order calculation, suppose they end up at each one of those 100 with uniform probability. BU has about 2,000 people per class, MIT has about 1,000.</p>
<p>Suppose 1/4 of MIT students have a serious significant other before coming to college. </p>
<p>The number of MIT-BU pairs will follow a binomial distribution. 250 draws, success with p=.01, failure with p=.99.</p>
<p>Using trusty MATLAB, the expected number of couples is 2.5. In almost half of the years you observe, you’d expect to see at least three couples. </p>
<p>(The expected number of couples is the sum of k *P<a href=“%5Bi%5Dk%5B/i%5D”>/i</a>, over all 0 <= k < 250.)</p>
<p>Ergo: I lied a little bit, but not that much, above, when I said the probability is about 1. Actually, it’s about a half. But a half is about one. At Caltech, at least.)</p>
<p>God, I love statistics.</p>
<p><em>laughs</em> I was just about to say the exact same thing. =]</p>
<p>To the original poster and to Crash, it is definitely manageable to maintain the relationship and have your BF stay over. For the most part, roommates are understandable when it comes to this, but you should make sure that they are ok before you room with them (you may want to switch during in-house rush). </p>
<p>Since they go to BU, it would pretty much always end up that they would stay over at MIT. BU has a very strict guest policy. You would have to be out of their room by 1 and if you ever wanted to stay over, you would have to have a person of your sex fill out a request form and submit it in advance. So, basically, he would just be coming to MIT all the time.</p>
<p>Ugh, so many rules at BU.</p>
<p>Here at MIT, we don’t believe in rules. ;)</p>
<p>haha anarchy!!</p>
<p>um, i had a nitpicky question. do most dorms have a guest list type thing, where a frequent guest will be let in without someone having to come down to do so? are there any dorms that are more lax about guest policies than others? i heard mccormick is more strict than some, but i dont really know much about other dorms.</p>
<p>I know for sure that some dorms have a guest list policy – you list your guests, they’re let in when they come. I’m not sure how prevalent that is.</p>
<p>Although most dorms try to be tough on security, the reality is that people who don’t live in the dorms get let in pretty frequently, no questions asked.</p>
<p>it’s hardest to get into mccormick if you don’t live there :P</p>
<p>Unless you’re a girl. If you’re a girl, you can walk right in. If you’re a guy, I suggest you get to know the desk workers. ;-)</p>
<p>wait, I’m a girl.</p>
<p>:/</p>
<p>Getting into EC kind of sucks if you don’t live there, since the each of the floors locks separately, so even if you get let in by a deskworker…you can’t actually get to your friend’s room.</p>
<p>At BC in general, if you wander in to the dorm with a bunch of people who do live there and just head on up to the floor you want to visit…ta da. Pretty simple.</p>
<p>I never heard anything about a guest list policy- generally if you ask the deskworker to be let into BC they’ll make you sign in as a security measure. But I am generally clueless, so we might have a guest list policy that I don’t know about. (Note to self- look into this…)</p>
<p>I just flirt with the deskworkers on the way into mccormick ;-o
or get on a guest list</p>
<p>Do ever of your current students have friends who cheated on their partner at MIT?</p>
<p>You mean cheated on a long-distance boyfriend/girlfriend while at MIT (yes), or cheated on an MIT boyfriend/girlfriend with someone else (check on that one too)?</p>
<p>hah, you can just enter through the fire escapes at EC :)</p>
