Scrabble. Using a computer to play many simulatedgames of Scrabble, researcher Charles Robinove foundthat the letter “A” occurred in 54% of the hands. Thisstudy had a margin of error of {10,. (Chance, 15,no. 1 [2002])a) Explain what the margin of error means in thiscontext.b) Why might the margin of error be so large?c) Probability theory predicts that the letter “A” should appear in 63% of the hands. Does this make you con-cerned that the simulation might be faulty? Explain.
