Could you pass a Cambridge University interview?

Lost on this question:

Q.8 An unbiased cubic die has numbers 1 to 6 inscribed on each side. On average, how many rolls will you need in order to get a 6?

Well I answered 1 instead of 6 given that the numbers 1 through 6 and inscribed on each side? But no...

Thickos can't even write the question properly.

Since I didn't get in (twice) I already know the answer is "no"

Shame, as I didn't feel I'd shown my best and got a bit flustered, but oh well. I got asked (IIRC):

"I have a cube where each edge is a resister of resistance R. What is the resistance between opposite corners"

That's a 3D Wheatstone bridge that is, which is equal to (1/r1*1/r4*1/7)+(1/r2*1/r5*1/r8)+(1/r3*1/r6*1/9) I think.

It's six surely? SAS will back me up and praise my thinking.....

As you say it's a trick question, they say it has 1 to 6 inscribed on each side

So the answer has to be 1,as each roll is guaranteed a six

If they don't mean that their question is invalid

That would be EVERY side, wouldn't it? It's a question of semantics....

I got 80%

But then I DID pass a Cambridge interview, back in 1988

Didn't know Cambridge had a Poly back then?

Sorry, SASguru mode on/off...

If it didn't have side it's wouldn't be a dice ergo they are wrong, each/every in this context still means the same thing their argument is still invalid

I got 20% but when I was six I didn't get a bike for Christmas so I got a place - yay!
