What numbers between 20 and 40 are divisible by 6?
24, 30 and 36.
What is the probability that a random selected number from 20 to 30 is divisible by 3 and then divisible by 12 after replacing first?
To find the probability of selecting a number from 20 to 30 that is divisible by 3, we first identify the numbers in that range: 21, 24, 27, and 30. There are four suitable candidates, so the probability of selecting one of them is 4 out of 11 (the total numbers from 20 to 30, inclusive). After replacing the selected number, we check which of these are divisible by 12. Among the numbers listed, only 24 is divisible by 12. Therefore, the probability of selecting a number divisible by 3 and then finding it divisible by 12 is 1 out of 11, which simplifies to approximately 0.0909 or 9.09%.
What number are divisible by 4?
4, 8, 12, 16, 20, 24, 28, 32, 36 . . . You can tell if a number is divisible by 4 by looking at the last two numbers, for example, is 1024 divisible by 4? To solve that, look at the last two numbers, 24. Is 24 divisible by 4? Yes, because 24 is a multiple of 4, so 1024 is divisible by 4!
Is 2 divisible by 24?
No, 2 is not evenly divisible by 24.
Is 1124 divisible by 4?
Yes 1124 is divisible by 4. Since 24 is divisible by 4 1124 is divisible by 4. If the last two numbers of a number are divisible by 4, the number is divisible by 4. 24 divided by 4 is 6.
