in a simple lottery system in which three one-digit numbers are randomly selected what is the probability of getting the first two numbers right and the last number wrong? (numbers can be repeated and 0 is allowed)
Homework Answers

number of ways of getting first two numbers right and the last number wrong =1*1*9=9
therefore probability of getting the first two numbers right and the last number wrong =9/1000=0.009
