Take any one of 100 integers and calculate the probability that this number can not be divided by 6 or 8
100 △ 6 = 16 more than 4
100 ÷ 8 = 12 more than 4
The least common multiple of 6 and 8 is 24
100 △ 24 = 4 and 4
1--100,
There are 16 divisible by 6
There are 12 that can be divided by 8
There are four that can be divided by 6 and 8 at the same time
Can be divided by 6 or 8, there are: 16 + 12-4 = 24
The probability of not divisible by 6 or 8 is: (100-24) △ 100 = 0.76

The probability that the product of the three integers can be divisible by 10 is obtained by randomly taking three times from nine integers from one to nine, one at a time I read the answers on the Internet, but I can't understand them, especially the ones with one five and two five. I don't know how to calculate the probability I thought there must be a 5 that is 1 / 9, there must be an even number 4 / 9, another random 9 / 9, but the multiplication is not right 214, why not? It's best to write the reason step Otherwise I can't understand it
