Statistics Continuous Random Variable Question?
I'm having a hard time with this statistics questions.
Let X denote the voltage at the output of a microphone, and
suppose that X has a uniform distribution on the interval
from -1 to 1. The voltage is processed by a “hard limiter”
with cutoff values -.5 and .5, so the limiter output is a random
variable Y related to X by
Y=X if -.5 ≤ X ≤ .5,
Y = .5 if X>.5 and
Y=-.5 if X<-5
a. What is P(Y=.5)?
b. Obtain the cumulative distribution function of Y and
graph it.
Insight appreciated. Will give best answer.

Let's say I have x number of unique marbles in a bag. I pick 10 out at random, then I put them back in the bag, mix it up, and take out 10 more. How could I figure out how many times I would need to pick out 10 marbles from the bag in order to have a high chance (say, above 95%) of having seen every unique marble in the bag.
Thank you

2 AnswersSoftware10 years agoWhat painting am I thinking of (description provided)?
I'm thinking of a painting with a model of a sailboat, about the size of a briefcase, on a table, in front of a window overlooking a large lake, bay, or ocean. There may be a lighthouse in the background and the overall tone looks a little pinkish. The perspective is from inside of a room, with the window in the middle of the perspective view.
Can anyone tell me what painting this is?

1 AnswerMathematics1 decade agoFor the 2014 Winter Olympics, how do they plan on doing it in Sochi, Russia, because of its warm climate.?
Sochi is a tropical city, a resort in Russia. They go there for vacations. I know from 1st hand accounts.
Also, According to Wikipedia
Sochi has a humid subtropical climate (Koppen climate classification Cfa) at the lower elevations, with an average January temperature of 6 °C (42.8 °F) and winter temperatures rarely falling below freezing. The average summer high temperature ranges between 25 °C (77 °F) and 28 °C (82.4 °F) with occasional extreme heat in some interior locations exceeding 40 °C (104 °F).
How are they going to the winter olympics in a tropical city? Not all of Russia is a pile of snow. Alternatively, they could've chosen St. Petersburg or Moscow.
