Wheel of Fortune! Use Table 16 for Exercises 74–81. Imagine yourself on the television game show Wheel of Fortune, where contestants guess the letters contained in a hidden phrase. You want to ask for the letters that have the greatest chance of occurring, so you want to know the various probabilities of the letters in the English alphabet.
The experiment is to choose one letter at random from a sample of 1000 letters. The sample space is the 26 letters of the alphabet. The total sample size is 1000, so you can find the relative frequencies of the letters in English simply by dividing each frequency by the total sample size (remember this from Chapter 2?).
