A= {a,b,c,d} B = { b,d,c,f} find AUB, A∩B, n(A), n(B), n(AUB), n(A∩B)
Ludmilka [50]
<u>Given</u><u> info</u><u>:</u>
A = { a,b,c,d }
B = {b,d,c,f}
Find the following :
1) AUB
2)AnB
3) n(A)
4) n(B)
5) n(AUB)
6) n(AnB)
<u>Solution :-</u>
Given sets are A = { a,b,c,d }
⇛ Number of elements in A = 4
⇛ n(A) = 4
B = {b,d,c,f}
⇛ Number be f elements in B = 4
⇛ n(B) = 4
AUB
⇛ {a,b,c,d} U { b,d,c,f}
⇛ {a,b,c,d,f}
AUB = {a,b,c,d,f}
⇛ Number of elements in AUB = 5
⇛ n(AUB) = 5
and
AnB = {a,b,c,d} n { b,d,c,f}
⇛ AnB = { b,c,d}
⇛ Number of elements in AnB = 2
⇛ n(AnB) = 2
<u>Answer</u><u>:</u><u>-</u>
1) AUB = {a,b,c,d,f}
2)AnB = { b,c,d}
3) n(A) = 4
4) n(B) = 4
5) n(AUB) = 5
6) n(AnB) = 3
Answer:
you didnt give answer choices
Answer:
9 of each
Step-by-step explanation:
9 x 10= 90
9 x 5= 45
9 x 1= 9
90 + 45 + 9= 144, now add a decimal
Answer:
Set Y I’m pretty sure
Step-by-step explanation:
No, a scalene has 3 unequal sides. so this would be a isosceles since you need to equal sides for a isosceles
