Suppose that we have a data set of doctoral students in economics. This data set includes whether each student had a major in economics from his or her undergraduate institution and whether the same student earned a master's degree before starting a PhD program. Also, this data set includes information on which subfield of economics the student is interested in. Let's define the events E, M, FMicro, FMacro, and FMetrics as follows: E = {Economics major} M = {Having a master degree} FMicro = {Choosing microeconomics as a sub-field} FMacro = {Choosing macroeconomics as a sub-field} FMetrics = {Choosing econometrics as a sub-field} FMicro FMacro FMetrics Total E∩M .150 .150 .100 .400 E∩MC .050 .075 .050 .175 EC∩M .050 .100 .050 .200 EC∩MC .050 .150 .025 .225 Total .300 .475 .225 1) Suppose we learn that a student got a major in economics.

Please! Could you help me solving this practice problem I’m having hard time with it.
Consider the Venn diagram below. Each of the dots outside the circle represents a biologist questioned about their research interests. 10 biologists are questioned about their research interests. Six biologists are marine biologists, represented by red dots and labeled M1,M2,M3,M4,M5,M6. Four biologists are zoologists, represented by blue dots and labeled Z1,Z2,Z3 and Z4. The two events represented in the Venn diagram are: Event A: The biologist is interested in studying insects. Event B: The biologist is interested in studying salmon habitats. The biologists who say they are only interested in studying insects are Z1,Z2,Z3,M5 and M6. The biologists who say they are only interested in studying salmon habitats are M1,M2,M3 and M4. The biologist who said they were not interested in either topic is Z4. Place the dots in the appropriate event given the information above (you may not use all of the dots), then determine if the events are mutually exclusive.
Q. 22 If A and B are independent events, how about the independence of their complements A and B?
A nationwide survey conducted by the National Cancer Society revealed the following information. Of 10,000 peoplesurveyed 3,200 were “heavy coffee drinkers”, and 160 of those surveyed had cancer of the pancreas. Of those who hadcancer of the pancreas, 132 were heavy coffee drinkers. Using the data in this survey, determine whether the events “beinga heavy coffee drinker” and “having cancer of the pancreas” are independent events.
d. Are events A and C mutually exclusive? - Select your answer - e. What is Bº? (i) {E1, E3, E5, E6} (ii) {E2, E4, E5, E7} (iii) {E3, E4, E5, Es} (iv) {E₁, E4, E6} (v) {E2, E4, E7} (vi) {0} - Select your answer - What is P(B)? If necessary round your answer to two deicmal places.
