Answer and Step-by-step explanation:
A = {l,m,n,o,p}
B = {o,p,q,r}
C = {r,s,t,u}
(A ∪ B) ∩ C
(A ∪ B) = {l,m,n,o,p,q,r}
C = {r,s,t,u}
(A ∪ B) ∩ C = {r}
A ∩ (C ∪ B)
(C ∪ B) = {o,p,q,r,s,t,u}
A = {l,m,n,o,p}
A ∩ (C ∪ B) = {o,p}
(A ∩ B) ∪ C
(A ∩ B) = {o,p}
C = {r,s,t,u}
(A ∩ B) ∪ C = {o,p,r,s,t,u}
At a newsstand, out of 46 customers, 27 bought the Daily News, 18 bought the Tribune, and 6 bought both papers. Use a Venn diagram to answer the following questions:
only daily news: 21 (27-6)
only tribune: 12 (18-6)
Total newspaper: 39 (21+12+6)
Other than newspapers: 7 (46 - 39)
How many customers bought only one paper? 21+12 = 33
How many customers bought something other than either of the two papers? 7
equal, equivalent, or neither.
{d,o,g}: {c,a,t} equivalent
{run} : {{r,u,n} equal
{t,o,p} :{p,o,t} equal
