The Puzzle
A car owner is very superstitious. He lives in a city where a combination of Alphabets and Numbers is assigned to car in registration. His only choice was not to have 3 in the car registration number. Firstly he thought there should very little chance of getting a number with 3 as its odds are only 1 out of 10. If the Format of registration number is AA DD AA DDDD, where A represents an alphabet from A-Z and D represents a digit between 0 to 9, what is the probability of not getting a number with 3 in its registration number?
Can you update him on chance of having a number without 3 in it?

Do you dare to try it !!
The possibility of occurrence of any digit except 3 at a single digit place is 9 out of 10 i.e 9/10.
ReplyDeleteAnd there are total six digit places, therefore
(9/10)*(9/10)*(9/10)*(9/10)*(9/10)*(9/10) = 0.5314
In other words we can say that 53.1 4% is the possibility of getting a number plate which does not have digit 3 in it.
