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
The answer is C) 30°, 30°, 90°
Hope this helps. :)

Answer:
575.8 cubic cm
Step-by-step explanation:
V(cone) = 1/3· π · r² · h
V = 1/3 · π · 25 · 12
V = 4(25)π or 100π = 314
V(half-sphere) = (4/3 · π r³)/2
V = (4/3π · 125) = 261.8
