Using three different digital cards to place three digits, the probability of being divisible by three is 100%, the probability of being divisible by five is 1 / 3, and the probability of being divisible by two is 0 2/3
If the probability of division by 5 is 1 / 3, then one of the numbers must be a number ending in 0 or 5. If the probability of division by 2 is 2 / 3, then two of the numbers are even
There are three cards with numbers 4, 5 and 0 written on them. Please use these three cards to form three digits. What numbers can be divided by 3 and 5 at the same time?
The three digit number composed of 4, 5 and 0 can be divided by 3 and 5 at the same time: 450405540
How many of the four digits composed of 1, 2, 3 and 4 can be divided by 11?
