P(a U b) = p(a) + p(b) - p(a ∩ b)
<=>
p(a ∩ b) = p(a) + p(b) - p(a U b)

Q 13 roots of equation

the roots of the second equation are
x1 = 1/3(-0.693) = -0.231
x2 = 1/3(1.443) = 0.481
the equation is
(x+0.231)(x-0.481)=0

Answer:
9x = 52
Step-by-step explanation:
Brandon + Michael = 2 + 7 friends = 9
x= number of cards each player receives
Solve it by simply dividing 52 by 9 which gives you x = 5.78
So there would be only enough cards for each player to have 5. Then 7 left over.
