000 to 999
0 through 9 0 through 9 0 through 9
10^3 = 1000
so
1/1000
I do not know what #3 means either
In a straight 3 lottery you choose a 3 digit number. A 3 digit number is chosen at random, If your number mataches you win $250.
1. How many diifrent three digit numbers are there? I thought you would do 3^3 but that only equaled 27 so i assumed im wrong
2. what is the proabiliy that your number is the winner
3. There are two outcomes in the sample space {$250,$0} using these write down a probaility model for the straight pick 3 lottery
