There are (500-100)/2 = 200 numbers divisible by 2 between 100 and 500 counting 100 but not 500. Of these (500-100)/8 = 50 are divisible by 8. So there are 150 numbers between 100 and 500 divisible by two but not by 8. By relative primeness exactly 50 out of these 150 are divisible by 3 and therefore these 50 are exactly the ones divisible by 6 but not by 8.
The prime numbers between 50 and 70 are: 53 59 61 67 Therefore, there are four prime numbers between 50 and 70.
To find the number of even integers between 100 and 1000, we first determine the number of even integers between 1 and 1000, which is half of the total integers (since every other integer is even). So, 1000/2 = 500 even integers between 1 and 1000. Next, we subtract the number of even integers between 1 and 100, which is 50 (since every other integer is even in this range as well). Therefore, there are 500 - 50 = 450 even integers between 100 and 1000.

there are 17 divisible by 3 between 50 to 100 , 51,54,57,60,63,66,69,72,75,78,81,84,87,90,93,96,99
There are 8 integers under 50 divisible by 6 and 6 divisible by 8. 24 and 48 are common multiples so there are 12 qualifying integers. Probability is therefore 12 out of 50 or 24%. (6,8,12,16,18,24,30,32,36,40,42,48.)

Well, honey, if you want to get technical, there are 36 integers between 13 and 50. But really, who's counting? Just take my word for it and move on with your day.
21 numbers - if you include the 10 and the 50.
24. 25 if you include 50.
Integers divisible by 8 have their last 3 digits divisible by 8. So: 2934829387957008 is divisible by 8 because the last three digits are divisible by 8 (008 / 8 = 1). 2348012934801298304400 is also (400 / 8 = 50). 123006 is not (006 / 8 = 0.75).
