Question 1173588: Please I need help with this problem, i just don't know how to solve it correctly...
A CBS News poll conducted June 10 and 11, 2006, among a nationwide random sample of 651 adults, asked those adults about their party affiliation (Democrat, Republican or none) and their opinion of how the US economy was changing ("getting better," "getting worse" or "about the same"). The results are shown in the table below.
better same worse
Republican 38 104 44
Democrat 12 87 137
none 21 90 118

Express your answers as a decimal and round to the nearest 0.001 (in other words, type 0.123, not 12.3% or 0.123456).
If we randomly select one of the adults who participated in this study, compute:
P(affiliated with neither party) =

P(worse) =

P(worse|affiliated with neither party) =

P(affiliated with neither party|worse) =

P(affiliated with neither party and worse) =

Hi,

Wish You the Best in your Studies.



	B	S	W	 Tot

R	38	104	44	186

D	12	87	137	236

O	21	90	118	229

Tot	71	281	299	651

If we randomly select one of the adults who participated in this study

Note: Necessary to have Tot entries to answer the following:

P(worse) = 299/651

P(worse|affiliated with neither party) = 118/229    P(A|B) = P(A and B)/P(B) =  

P(affiliated with neither party|worse) =  229/299   P(A|B) = P(A and B)/P(B) 

P(affiliated with neither party and worse) =  118/651

will leave the calculator work and rounding to the nearest 0.001 to You
