If the odds in favor of an event B are x to y, what is the probability that event B will occur?

Question 2

A meteorologist predicts that there will be a measurable amount of precipitation or no precipitation on a given day. The sample space is S = precipitation, no precipitation. Event A is defined to be A = precipitation. A student uses P(A) = n(A)/n(S) to obtain P(A) = 0.50 . Explain why this is not correct.

Answer to Question 1

P(B) = x / (x + y)

Answer to Question 2

The formula P(A) = n(A)/n(S) cannot be used since the sample points are not equally likely to occur.
