A website reports that 70% of its users are from outside a certain country and 50% of its users log on to the website every day. Suppose that 10% of its users are from the country and log on every day. What is the probability that a person is from the country given that he logs on to the website every day? Has the probability that he is from the country increased or decreased with the additional information? The probability that a person is from the country given that he logs on to the website every day is .2 (Type an integer or a decimal. Do not round.) The probability that the person is from the country is so the probability has decreased when given the additional information that the person logs on every day. (Type an integer or a decimal. Do not round.) S (0,0) E More
