a) an unfavorable opinion of capital punishment given that they have untapped math skills.
b) an unfavorable opinion of capital punishment or untapped math skills.
c) an unfavorable opinion of capital punishment and untapped math skills.
d) an unfavorable opinion of capital punishment.
e) untapped math skills.
f) untapped math skills given that they have an unfavorable opinion of capital punishment.
g) Is there an apparent relationship between one’s opinion of capital punishment and math skills? Provide evidence and describe any relationship.
+129899 I think I can do a few, GM
a) P ( UF l UT) = 86 / ( 77 + 87 + 86) = 86 / 250 = 43 / 125
b) P ( UF or UT) = P ( UF U UT) = P(UF) + P( UT) - P(UF ∩ UT) =
(86 + 21) 250 86 21 + 250 271
________ + _____ - _____ = _________ = ____
300 300 300 300 300
c) P (UF and UT ) = P(UF ∩ UT) = 86/300 = 43/150
d) P(UF) = (86 + 21) / 300 = 107 / 300
e) P (UT) = (250)/300 = 25/30 = 5/6
f) P ( UT l UF ) = 86 / (86 + 21) = 86 / 107
g) It appears that the greater one's math skills, the less one supports capital punishment
Ex :
89 people had a favorable opinion of capital punishment
77 of these had untapped skills = (77/89) = 86.5%
But only 12 had max skills = (12/89) = 13.5%
+73 Thanks again, CPhill, for your efforts! I didn't know how to approach this kind of problem, so I needed help to learn about this probability issue. I also posted another math problem similar to this one that you can check out here.
