RE: PROBABILITY - Using Tree Diagrams To Find The Sample Space
That is similar to the subject, I was teaching lately. Kids asked me what means exclamation mark after the number? (example: 7!) And I told them...let's say we have 7 different cars, and if you should calculate number of all possible sequences of those cars, how would you do it? Answer is : 7x6x5x4x3x2x1 = 5040 So those 7 cars could be parked in 5040 different sequences. And we write that down as 7!=5040
Right @worldfinances, very well explained factorial notation :))
