A Bloom Filter consists of bits of memory and uniform and independent hash functions
dots, Each hashes a key to an integer in the range Initially all filter bits are
zero, and the data set is empty. When key is added to the data set, bits dots, of the
filter are set to When a query Is key in the data set?" is made, bits dots, are
examined. The query answer is "maybe" if all these bits are Otherwise, the answer is no A
filter error occurs whenever the answer is "maybe" and the key is not in the data set. Assume that
key is an integer in the range and updates are made. Compute the probability of filter error
for an arbitrary query after the uth update.
