4. One hundred students were surveyed and asked if they are currently taking math (M), English (E) and/or History (H) The survey findings are summarized here: Table 1.2: Survey Results n(M) = 45 n(E) = 41 n(H) = 40 n(M ? E) = 15 n(M ? H) = 18 n(M ? E ? H) = 7 n[(M ? E) ? (M ? H) ? (E ? H)] = 36 (a) Use a Venn diagram to represent this data. (b) How many students are only taking math?

A group of 30 students were surveyed and it was found that 18 of them took Calculus and 12 took Physics If all students took at least one course how many took both Calculus and Physics? Illustrate using a Venn diagram What is the answer to the question in part (a) if five students did not take either of the two courses? Illustrate using a Venn diagram
