Choose a natural number between 1 and 30, inclusive. What is the probability that the number is a multiple of 3?

  • ALGEBRA - ,

    multiples of 3 are
    3 6 9 12 15 18 21 24 27 and 30
    that is, there are 10 of them
    so prob = 10/30 = 1/3

    (makes sense, just like the prob that picking a number from 1 to 40, which is a multiple of 4 would be 1/4)
