discussions about the innocence of a young boy are decided. The dark and foreboding storm clouds that hang over the heads of the jurors are beginning to lift as time progresses and new facts are presented. The two men that cannot put their personal emotions aside are juror 3 and juror 10. These men are motivated by their emotions rather than the evidence. Juror 3 is a strong‚ forceful man who refuses to alter his vote. Being very opinionated‚ he looks at the evidence “you sat right there in court and heard

In the play Twelve Angry Men‚ the playwright Reginald Rose demonstrates through the characters of the jury the conflict between right and wrong and what can come from that conflict.

Rose intentionally creates the characters of the jury to have contradicting values to show how conflict is often necessary before justice can be served. The only way to give the accused a fair trial is if there is conflict occurring between

MOMENTS OF A RANDOM VARIABLE Definition: Let X be a rv with the range space Rx and let c be any known constant. Then the kth moment of X about the constant c is defined as Mk (X) = E[ (X c)k ]. (12) In the field of statistics only 2 values of c are of interest: c = 0 and c = . Moments about c = 0 are called origin moments and are denoted by k‚ i.e.‚ k = E(Xk )‚ where c = 0 has been inserted into equation (12). Moments about the population

Comparison essay comparing Juror 3 and Juror 8 What are some similarities between Jurors 3 and 8? What about differences? Oh gosh‚ it’s been years since I’ve seen the movie (didn’t read the play). Okay‚ Juror #3 is the angry father‚ and Juror #8 is the guy who stands alone in the INNOCENT vote‚ right? I suspect the similarities are easier to find by reading the play because the movie really shows their contrasts. There is one similarity in that when they really believe something‚ they

I noticed when entering the theatre that there were small‚ blue lights hanging off the ceiling and the stage
