bike race

Steven has registered in a 60 km bike race. There are 44 other people in the race. Steven has a favorite 3 digit number of 111. He wants to know what the probability of getting this number is. Can you tell him the answer?



Solution: there are only 9 possible numbers for the first digit (1-9)
there are 10 possible digits for the last two digits (0-9)
To find the answer: 9x10x10=900 possible three digit numbers
