Teacher's Notes Topic: Probability Vowels A computer is going to choose a letter at random from an English book. The table shows the probability of the computer choosing each vowel. Vowel A E I O U Probability 0.08 0.13 0.07 0.08 0.03 (a) What is the probability that it will not choose a vowel ? L6 What other questions could you answer ? Eg p(A or E) = 0.21 p(I or O or U) = 0.18 etc (b) The probability that the computer will choose the letter T is 0.09 The computer chooses a letter at random, and then another, and then another.
