Two Web colors are used for a site advertisement. If a site visitorarrives from an affiliate, the probabilities of the blue or green colors being used in the advertisement are 0.6and 0.4, respectively. If the site visitor arrives from a search site, the probabilities of blue and green colors in the advertisement are 0.1and 0.9, respectively. The proportions of visitors from affiliatesand search sites are 0.3 and 0.7, respectively. What is the probability that a visitor is from a search site given that the blue ad was viewed?

Write a program that prints the day number of the year, given the date in the form month-day-year. for example, if the input is 1-1-2006, the day number is 1; if the input is 12-25-2006, the day number is 359. the program should check for a leap year. a year is a leap year if it is divisible by 4, but not divisible by 100. for example, 1992 and 2008 are divisible by 4, but not by 100. a year that is divisible by 100 is a leap year if it is also divisible by 400. for example, 1600 and 2000 are divisible by 400. however, 1800 is not a leap year because 1800 is not divisible by 400.
