Of his random sample of students, 72 said they would vote yes, 90 said they would vote no, and 18 were undecided. Using these observed frequencies, develop a probability model for Kevin randomly choosing one more student for the poll. Enter the probabilities as decimals.

One integer is 8 times another. if the product is 72, then find the integers
