Accepted Solution

A:

Answer:The probability that you will get a 3-digit combination correct is: 1/720Step-by-step explanation:We are asked to find the probability that you will get a 3-digit combination correct if no digits in the combination can be repeated.Now the favorable number of outcomes=1 (which is the correct combination)Total number of outcomes= 10×9×8 (first place has 10 choices of digits from 0-9 ,second has 9 choices excluding the one at first place and third place has 8 choice) =720Probability= number of favorable outcomes/total number of outcomes = 1/720
