You are told that n(U) = 180 . . n(A' B'n c') = 20 n(An B'n c') = 8 n(ANC) = 15 n(A'n Bn C) = 11 Choose values for n(A), n(B) and n(C) which are consistent with the above constraints. (For example, you cannot choose a value for n(A) which is larger than n(U) because this is impossible.) Note: do not calculate these values by choosing values for other regions in the Venn diagram or full marks will not be awarded in this question. Using your values, find: (1) n((AUB)') **(ii) n(A'n B) **(iii) n((AnBn C) U B') [2] [2] [2] You are told that n(U) = 180 . . n(A' B'n c') = 20 n(An B'n c') = 8 n(ANC) = 15 n(A'n Bn C) = 11 Choose values for n(A), n(B) and n(C) which are consistent with the above constraints.
