To get the probability of selecting a person who is a
democrat and is favour to the issue, let us first calculate for the portions in
each party who is favour on the issue.
p (rep & favour) = 0.4 * 0.3 = 0.12
p (dem & favour) = 0.6 * 0.7 = 0.42
Therefore the total portions who are favour is:
p (favour) = 0.12 + 0.42 = 0.54
Hence the probability is:
P (dem & favour) = 0.42 / 0.54 = 0.7778 = 0.78
Therefore there is about 78% probability that the person
selected who is favour to the issue is a democrat.
Answer:
x = 53
Step-by-step explanation:
angle 3 + angle 8 = 180 because of linear pair
66 + 2x + 8 = 180
74 + 2x = 180
2x = 180 - 74
2x = 106
x = 106/2
x = 53
X is 7 obiviously because when you subtract 5 from both sides you are gonna have 7 for x
