Answer:
a. 256
b. 255
Step-by-step explanation:
If a set has “n” elements, then the number of subset of the given set is [tex]2^n[/tex] and number of proper subset is [tex]2^n-1[/tex]
A = {3, 4, 5, 6, 7, 9, 10, 11}
Here, n = 8
No of subsets
[tex] = {2}^{n} = {2}^{8} = 256[/tex]
No of proper subsets
= [tex]2^n-1 = 256-1=255[/tex]
