Answer:
The expected number of days until prisoner reaches freedom is 12 days
Step-by-step explanation:
From the given information:
Let X be the random variable that denotes the number of days until the prisoner reaches freedom.
We can evaluate E(X) by calculating the doors selected, If Y be the event that the prisoner selects a door, Then;
E(X) = E( E[X|Y] )
E(X) = E [X|Y =1 ] P{Y =1} + E [X|Y =2 ] P{Y =2} + E [X|Y =3 ] P{Y =3}
Solving for E[X]; we get
E[X] = 12
13% of 4,760,000 = 618,800
4,760,000 + 618,800 = 5,378,800

Volume of a Cylinder = πr²h
v = 3.14 * (0.5)² * 2.5
v = 3.14 * 0.25 * 2.5
v = 1.96 Ft³
In short, Your Answer would be 1.96 Ft³
