How many different numbers can you make if you use the digits 1, 2, 3, 4 once each, in any order, and a times sign. For instance 31x24, or 2x413.
You are driving and come to a fork in the road. You need to get to New York City. The roads do not have signs, no one is there to tell you which road you need to take, and you can't turn back and take the other road if you take the wrong one the first time. You can not turn around a go a different way. If you randomly choose a road to take how will you know you are choosing the correct road before you take it? What is the chance you will take the correct road?
