solve this question for a salute
a circle is drawn passing through three different points.
find the probability that all of them lie in the same semicircle.
|
 
Being beaten is often a temporary condition, giving up is what makes it permanent. |

the question is very good but wat comes to my mind is sunfink very stupid but logical...............the case when 3 points lie on the same semicircle the triangle has to be scalene or at the most right angles since angle ina semicircle is a right angle now how do i find the probability of this.................

let the first point be selected anywhere on the circle.
the chance that the second point lies in that semi-circle is 1/2.
similarly,
the chance that the third point lies in that semi-circle is 1/2.
hence, reqd. probability=1/2 x 1/2
=1/4.
