You toss two number cubes. If a sum of 7 or 11 comes up, you get 7 points, if not you lose 2 points.

The probabilities for each of the sums is:

P(2) = 1/36 P(3) = 1/18 P(4) = 1/12 P(5) = 1/9

P(6) = 5/36 P(7) = 1/6 P(8) = 5/36 P(9) = 1/9

P(10) = 1/12 P(11) = 1/18 P(12) = 1/36

The probability of a sum of 7 or 11 is:

Answer:

  • 2/9

Step-by-step explanation:

The probability of a sum of 7 or 11 is the sum of each probability:

  • P(sum of 7 or 11) = P(7) + P(11) =
  •                              1/6 + 1/18    =
  •                              3/18 + 1/18  =
  •                              4/18            =
  •                              2/9
