To determine the probability that a randomly chosen number from one to twelve is a divisor of twelve, we first need to identify all the divisors of twelve. A divisor of twelve is any number that divides twelve without leaving a remainder. The divisors of twelve are: 1,2,3,4,6,12. There are a total of six divisors of twelve. Next, we note that the total number of possible choices (from one to twelve) is twelve. The probability P that a randomly chosen number from one to twelve is a divisor of twelve is given by the ratio of the number of favorable outcomes (divisors) to the total number of possible outcomes:
P=‌
‌ Number of divisors of ‌12
