Q.3.1 Determine the % marks that the students obtained for each of the tests, given that: Q.3.1.1 The Maths test was out of 200 marks. Determine this by entering an appropriate formula in cells C2 to C9. Q.3.1.2 The Science test was out of 60 marks. Determine this by entering an appropriate formula in cells E2 to E9. Q.3.1.3 The English test was out of 80 marks. Determine this by entering an appropriate formula in cells G2 to G9.
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.
