So I need to know the answer to this question.
A positive multiple of 45 less than 1000 is randomly selected. What is the probability that it is a two-digit integer? Express your answer as a common fraction.
If you explai how to solve this prolem it will help me a lot.
Well, Look at this list:
45 90 135 180 225 270 315 360 405 450 495 540 585 630 675 720 765 810 855 900 945 990 Total No = 22.
As you can see, there are 22 numbers between 45 and 1000 that are multiples of 45. But, only 2 of them
have 2 digits, 45 itself and 90. So, the probability would be:
2 / 22 =1 / 11 That a randomly picked number will be a 2-digit number.
