Take any three of the 10 numbers from 0 to 9 to form a three digit number without repetition. The probability that this number cannot be divided by 3 is______ ．

According to the meaning of the question: all the three digits have 9a92 = 648, and then according to the meaning of the question, the 10 digits are divided into three groups: 1, 4, 7 divided by 3 and 1; 2, 5, 8 divided by 3 and 2; 3, 6, 9, 0 divided by 3

16. 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
