MP E What does the following mean? Probability a student studies mathematics

MP E What does the following mean? Probability a student DOESN’T study mathematics

MP E What does the following mean? Probability a student mathematics OR physics

MP E What does the following mean? Probability a student mathematics AND physics

MP E What does the following mean? Probability a student mathematics AND NOT economics

MP E What does the following mean? GIVEN THAT the student studies economics, what is the probability they ALSO study mathematics

A market researcher asked 100 adults which of the three newspapers A, B, C they read. The results showed that 30 read A, 26 read B, 21 read C, 5 read both A and B, 7 read both B and C, 6 read both C and A and 2 read all three. (a) Draw a Venn diagram to represent these data.(6) One of the adults is then selected at random. Find the probability that she reads (b) at least one of the newspapers,(2) (c) only A,(1) (d) only one of the newspapers,(2) (e) A given that she reads only one newspaper. (2)

AB C A market researcher asked 100 adults which of the three newspapers A, B, C they read. The results showed that 30 read A, 26 read B, 21 read C, 5 read both A and B, 7 read both B and C, 6 read both C and A and 2 read all three. (a) Draw a Venn diagram to represent these data.(6)
