Answer:
Given that,
B={5,10,15,20,25,30}
To find the number of subsets does the set B have.
we get that,
The number of subsets does the set B have s nothing but the number of possible ways (Combination) where n=0,1,2,3,4,5,6
Let the number of subsets does the set B have be n(B)
[tex]n(B)=6C_0+6C_1+6C_2+6C_3+6C_4+6C_5+6C_6[/tex][tex]n(B)=1+6+15+20+15+6+1[/tex][tex]n(B)=64[/tex]The number of subsets B have is 64.
Answer is: 64
