Figiire 13. Fishing situation in which each fisherman 

 fishes the same expected time. 



A consistent estimate of 

 probability that any (unspecified) 

 the driving path. 



p is still k^j^/f . J , and p can be regarded as the 

 pecified) verticle line will be intersected by 



Figurelii is equivalent to Figure 13. In Figure lU, each verticle 

 line is replaced by a point at its center, the driving path diagnol is 

 replaced by a strip of width E(t), and the rectangular area is enlarged 

 by an amount one-half E(t) at top and bottom. Now, p is the probability 

 that a given point will fall within this strip.
