Anumber is chosen at random from 1 to 50. find the probability of selecting divisors of 12

Hi! 

First of all, we need to know how many divisors 12 has. 

12: 1, 2, 3, 4, 6, 12

Since there are 6 divisors of 12, this means the probability is 6/50. 

You could just stick with 6/50 as your answer, but most probability is measured in percents so we'll convert 6/50 into a percent. 

Percents are measured out of 100, so to make 6/50 into a percent we need to do some cross-multiplying. 



First, multiply 6 by 100

6 × 100 = 600

Next, divide the product by 50.

600 ÷ 50 = 12

So, your final answer is:

As a ratio:

 

As a fraction:

12/100 or 6/50

As a percent:

12%

Hope this helps!

Yes, that is the correct formula. to solve this problem given the number of years, plug in the number of years for t and plug the whole thing into the
