Each letter of the alphabet is written on a separate piece of paper and placed in a box. Find the probability of drawing a vowel, {a, e, i, o, u}, or a letter in the word "sum"

  • mtha - ,

    5/26 probability of drawing a vowel
    3/26 probability of drawing s, u or m.

  • math - ,

    Either-or probabilities are found by adding the individual probabilities.

  • mtha - ,

    This is not the right answer as you would not count the u in "sum" twice. Your answer is 7/26
