The probability that students will enter a building that is not  a multiple of 12 is 13/14

Probability is the likelihood or chance that an event will occur. Mathematically;

Probability = Expected outcome/Total Outcome

If a campus contains buildings numbered 1 through 70, then;

  • total outcome will be 70 buildings.

Multiple of 12 is 12, 24, 36, 48, 60 (5 buildings)

Buildings that are not multiples of 12 are 65 buildings. Hence;

  • Expected outcome = 65

Get the required probability:

Pr( student will enter a building that is not  a multiple of 12) = 65/70

Pr( student will enter a building that is not  a multiple of 12) = 13/14

Hence the probability that students will enter a building that is not  a multiple of 12 is 13/14.
