The list of girls suitable for at least one of the two boys must have at least two girls (else there would be a tie and only one of the two boys can get married). In general, given any subset of . boys, the list of all the girls suitable to at least one of

The inclusion-exclusion principle,of 2, 33 that are multiples of 3 and 20 that are multiples of 5. This certainly amounts to over-counting as there are integers that are divisible by two of the given three numbers 2, 3 and 5. In fact, the number of integers divisible by both 2 and 3 is 16, the number of integers divisible by both 2

Random variables,nterested in “how many chocolates” than the question of probabilities of heads and tails. Note that the emphasis is now shifting from the sample space Ω to something else. Consider one more example. This time, we toss an unbiased coin 20 times, where . pays . Rs. 4 if heads appear and . pays . Rs. 2

Permutations,tailed study of permutations. For a positive integer ., let . = . ⋯ . represent a permutation on [.] = {1, 2,…, .}. This simply means . takes . to . for every .. For a better combinatorial insight of a permutation the two line or one line representation is not very useful. We therefore need a differ
