### Re: Probability problem.

Did I say Happy New Year to you?

In mathematics, you don't understand things. You just get used to them.
Some cause happiness wherever they go; others, whenever they go.
If you can not overcome with talent...overcome with effort.

No, happy new year to you too!

Anyway, let's not discriminate the days!!

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 ?
