Web5 Oct 2024 · Any subset satisfying the condition is determined by its parts consisting of odd and even numbers, which are: an arbitrary two-element subset of $\{ 1, 3, 5, 7, 9 \}$; an arbitrary subset of $\{ 2, 4, 6, 8 \}$. The first part can be formed in $\binom{5}{2} = 10$ ways, the second part in $2^4 = 16$ ways. Hence there are $16 \cdot 10 = 160$ such ...

WebThe number of subsets of {1,2,3,...9} containing at least one odd number is : A 324 B 396 C 496 D 512 Medium Solution Verified by Toppr Correct option is C) The given subsets {1,2,3,....9} So, there are total 2 9 subsets of {1,2,3,...9} The even subsets will be {2,4,6,8} So, there are 2 4 even subsets of {2,4,6,8} Web10 Dec 2024 · Therefore, there are 2^8 subsets in the given set. Since the prime numbers are 2, 3, 5, and 7, the numbers in the set that are not primes are 1, 4, 6 and 8. The number of subsets these 4 numbers can create is 2^4. Therefore, the number of subsets with at least one prime number is 2^8 - 2^4 = 256 - 16 = 240. Answer: E. WebTotal subsets is Using complementary counting and finding the sets with composite numbers: only 4,6,8 and 9 are composite. Each one can be either in the set or out: = 16 -goldenn Solution 5 We multiply the number of possibilities of the set having prime numbers and the set having composites. hd lb2.0tu3
