For each probability and percentile problem, draw the picture. 

Births are approximately uniformly distributed between the 52 weeks of the year. They can be said to follow a uniform distribution from one to 53 (spread of 52 weeks).

Find the probability that a person is born at the exact moment week 6 starts. That is, find 

P(x = 6). (Enter your answer to four decimal places.) 

P(x = 6) =
