5. PLE as A, B, C? Each of the small squares in the grid below contains either A, B or C. Every row, every column and each of the two long diagonal lines of six squares contains exactly two of each letter. The information in the clues refers only to the squares in that row or column. To help you solve this problem, we've given as many clues as we think you'lIl need! Can you tell which letter should be placed into each square? Across: Down: 1. The Bs are somewhere between the Cs. 1. The Bs are lower than the Cs. 2. Any three consecutive squares contain three 2. One B is immediately next to and above one of the Cs and the other B is immediately next different letters. 3. The Bs are further right than the As. 4. Each C is immediately next to and right of an to and below the other C. 3. The As are somewhere between the Bs. A.
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
