The probability is low because of the "shape" that is generated.
The production of a straight line in natue is rare, although, it seems that "narrow" lines (1 - 2px) are indeed produced by cosmic rays, as can be
seen in the image I referenced. However the "broader" lines (>= 2 - 3px) are not seen. I've seen others and this seems to be the "rule".
In this and others there are two broad, very straight intersecting lines, which can be rotated to produce the "triangle". In every case I've seen
the "triangle" is actually the same shape (roughly equalateral).
Once is Nature telling us how stupid we are.
Twice is an OMG event. Because of the virtual impossibility of the second event.
three; One must consider other factors that ay cause the same effect.
More than that, it is amlost certainly an object. In a case such as this; the probability of there being an object becomes much greater than simply a
random event.
Does One
really need all sides of a shape to recognize that shape? In this case we have two sides of a triangle. I can rotate that triangle,
measure its existing sides and angle, then compute the third.
In short: there is enough information in that small bit of image to deduce that it
is a triangle shaped object.
