Answer to Problem 48PPE
There are
Explanation of Solution
Given information:
In one state , a regular license plate has a two-digit number that is fixed by country, then one letter, and then four one-digit numbers.
Formula used:
For any positive integer
Calculation:
According to the question,
Since license number is formed by using numbers and alphabets. It consist of 7 −digit license plate.
So, first two digits are fixed by the country. Now there are 5 digits to occupy.
For third place the possibility is 26. As after two digits , one alphabet is to be placed.
For fourth place the possibility is 10 . As numbers are placed from 0 to 9.
For fifth place the possibility is 10. As numbers are placed from 0 to 9.
For sixth the possibility is 10. As numbers are placed from 0 to 9.
For seventh the possibility is 10. As numbers are placed from 0 to 9.
Therefore,
Hence, there are
b.
To calculate: the number of license plates possible in the entire state.
