Math (Grade 12 Data Management)

posted by .

A student is asked to make up a 6 digit number by arranging the digits 111223. What is the probability that he will pick a number that has the 2's separated?

  • Math (Grade 12 Data Management) -

    Total number of arrangements = 6!/(3!2!)
    = 60

    No of ways where the 2's are together
    = 5!/3!
    = 20

    so the number of ways the 2's are apart
    = 40

    so the Prob(the 2's are separated) = 40/60
    = 2/3
