Answer:
Solution:Bayes:E1: Stock performs much better than the market averageE2: Stock performs same as the market averageE3: Stock performs worse than the market averageA: Stock is rated a ‘Good Buy’Given thatP(E1) = .25,P(E2) = .5,P(E3) = .25,P(A| E1) = .4,P(A| E2) = .2,P(A| E3) = .1Then,
P A EP EP EAP A EP EP A EP EP A EP E=++=(.40)(.25).444(.4)(.25)(.2)(.5)(.1)(.25)
No because when you cross multiply 9/24 has a bigger number
5x^2= x^2+64
-x^2= -x^2
4X^2= 64
Divide by 4
X^2= 16
X= positive 4 and negative 4
