Answer:
a) 0.6
b) 0.3
Step-by-step explanation:
Since we are taking 3 from a sample of 5 without replacements, we would have 5 choices for the first pick, 4 choices for the 2nd pick and 3 choices for the 3rd pick. The total possible number of ways to do this is:
5*4*3 = 60 ways
As order does not matter (GLS is the same as GSL), we divide this by the number of ways the 3 picks can be arrange, which is 3*2*1 = 6
So there are 60/6 = 10 possible samples
(a) If the governor is included in the sample, then we only have 4 choices for the 2nd pick and 3 choices for the 3rd pick. And there are also 2 ways to arrange this.
So there are 4*3/2 = 6 possible samples. The probability of this happening is 6/10 = 0.6
(b) If G and A are included, we only have 3 choices for the last pick. So the probability of this to happen is 3/10 = 0.3
D.d=24%
d.r=29%
d.t=53%
r.d=24%
r.r=24%
r.t=47%
t.d=47%
t.r=53%
t.t=100%
Just take the numbers and divide them over the total amount which in this caase is 51.
Answer:
<h2>v = 0</h2><h2 />
Step-by-step explanation:
-7 + 4v = -7v -7(1 - 6v)
⇔
-7 + 4v = -7v - 7 + 42v
⇔
4v = -7v + 42v
⇔
4v = 35v
⇔
35v - 4v = 0
⇔
31v = 0
⇔
v = 0
