Re: Probability problem.

Did I say Happy New Year to you?

Re: Probability problem.

No, happy new year to you too!

Anyway, let's not discriminate the days!!

Re: Probability problem.

v) What's the probability that the second highest number lies in between 3/11 and 7/13 ?
What about probability of 0<n1<{the second highest no.}<n2<1 ?

Re: Probability problem.

Can the other numbers lie in that range?

Re: Probability problem.

Hi,

More, more, morrrrre!

Thirteen numbers are selected randomly from U(0,1). What is the
1) expected sum of the top four numbers?
2) expected sum of the bottom four numbers?

Hi;

Yikes, wait for the old guy to catch up. I do not go up the hill so fast anymore. I am drawing a blank on vi. Do you have a solution?
