Take any number from 1 to 100 and find the probability that the number can be divided by 2 or 3
There are 50 multiples of 2, 33 multiples of 3, 16 common multiples of 2 and 3, 50 + 33-16 = 67, so the probability of being divisible by 2 or 3 is 67 / 100

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
