I know it might sound harsh. I hesitated to disguise my question using another context but I hope some can analyse the exercice despite the emotion.

I would understand also if you can't. If mods think i am out of line, please delete the exercice.

Lets consider the following 3 hypothesis:

**t**=Probability to be a terrorist= 10^-7**p**=Probability to not have a fb profile=10^-2- The last 3 known terrorists had no facebook account.

With

**T**=P(t/p) - Probability of being

**t**knowing

**p**

can we restrict the range of possible values of

**T**with an 90% confidence ?

For example, with a 100% confidence, we know

**T**is included between 0 and 100.

**t.**

I have already got some partial results but i don't want to influence the way you may solve the question. I am still struggling to conclude anyway.
