Webstring are numbered from zero up to the number of bits in the string less one, in right to left order, (the rightmost bit is numbered zero). When you convert from a bit string to an integer, the zero-th bit is associated with the zero-th power of two, the first bit is associated with the first power, and so on. WebDec 20, 2024 · Now there are 16 distinct digits that can be used to form numbers: {0, 1, …, 9, A, B, C, D, E, F}. So for example, a 3 digit hexadecimal number might be 2B8. How many 2-digit hexadecimals are there in which the first digit is E or F? Explain your answer in terms of the additive principle (using either events or sets).

WebBitstrings represent subsets of sets where a 1 means the corresponding element of your set is included in your subset, and 0 means it is excluded from your subset. For example, take the set {1, 2, 3, 4} and let the first bit in our bitstring correspond to 1, the second to 2, the third to 3, and the fourth to 4.
WebRelations are generalizations of functions. A relation merely states that the elements from two sets A and B are related in a certain way. More formally, a relation is defined as a subset of A × B.
