A number is selected at random from the set {1,2,3, ...,1000}. What is the probability that it is divisible by 19?

the probability is %5.2

Step-by-step explanation:

To know the probability that it is a multiple of 19 we have to know the number of multiples that 19 has between 1 and 1000. And that amount divide it by 1000. Finally we multiply it by 100 and we will have the percentage.

To know how many multiples there are from 1 to 1000 we have to make 1000 divided by 19 and the number that we get the decimals.

1000/19 = 52.63

there are 52 multiples

100*52/1000 = 5.2

the probability is %5.2
