rofl!!!

 

If length A is 2m.

And B is 2 times longer than A.

How long would A be if B was 8?

 

10 metres away from someone is a circle with a diameter of 1 metre. The idea is that he chooses a completely random number from -90 to +90 (relative to the target) and uses this number as his direction in degrees.
Each 'occasion', he walks 2 metres, before he has to stop and take a break. Of course, he may easily miss his target (and since there is no going back thanks to only 180 degrees of movement), what's the chance he will hit it?

Well I expect a answer as soon as you log on.
