A weather forecaster reports the following: P(rain today) = 0.30, P(rain tomorrow) = 0.40, P(rain both today and tomorrow) = 0.20, P(rain today or tomorrow) = 0.60. Define an appropriate sample space, write these expressions in terms of unions and intersections of subsets of the sample space, and assess if this is a reasonable statement to make.
