U = {a, b, c, d, e, f, g, h}, A= {a, b, c, d, e) and B= {c, d, e, f, g),
now,
A-B = {a,b}
A n B = { c,d,e}

One scarf=s
One hat=h
2s+h=13
s+2h=14
h=13-2s
(plug that into the other equation)
s+2(13-2s)=14
s+26-4s=14
26-3s=14
-3s=-12
s=4
One hat=$5
One scarf=$4
5+4=9
Price of one hat AND one scarf is $9
This problem can be solve using the Binomial Distribution, it is a recurrence conveyance of the conceivable number of effective results in a given number of trials in each of which there is a similar likelihood of accomplishment.
Let be X: coffleton residents recognize the brand name
n = 10
p = 0.53
q = 0.47
P(X = 4) =
(10)
(4)*(0.53^4)*(0.47^6) = <span>0.00340</span>
