Three points are selected at random on a sphere's surface. What is the probability that they all lie in the same hemisphere?
Assume that the great circle, bordering a hemisphere, is part of the hemisphere.
No matter how we place the points on a sphere it will without any doubt fall in one of the infinite possible hemispheres that can be chosen.
So the asked probability is 1 ie., 100%.
In space, the three points define a plane cutting the sphere in two pieces. The smaller of these two spherical caps is always contained in half of a sphere: a hemisphere.
Thus the answer is: 100% probable.
