Let The Wall Street Journal be A, and USA Today be B. We want
P(A∩B^c), or the intersection of A and Not B happening.
P(A∩B^c)=P(A∪B)-P(B) = [P(A)+P(B)-P(A and B)]-P(B)
=(0.45+0.40-0.25)-0.40 = 0.2.
I'm sorry my friend but I need as much help as you do I'm just answering this so I can get some help sorry
X^2 + 30x + 21
= ( x + 15)^2 - 225 + 21
= (x + 15)^2 - 204
Its D minimum at -204
$0.95 I think... all u need to do is divide the $38 by 40 and you’ll get $0.95 as the answer
