76. There are 13 different candies. In how many ways can a set be formed containing an odd number of candies
76. The total number of sets containing candies taken from the given 13 candies is equal to the number of subsets of a set of 13 elements, i.e., $2^{13}$ (see problem 48). Each subset with an odd number of elements corresponds to a subset with the remaining even number of elements. Therefore, the number of subsets with an odd number of elements will be half of the total number of subsets. Answer. $2^{13}$ : $: 2=2^{12}$.
