A car license plate is made up of 7 letters or numbers, where the numbers are whole numbers 0 through 9.
Simora [160]

Answer:

0.28

Step-by-step explanation:

To know the probability we first need to know the total number of choices for each character in the license plate. Since there are a total of 10 possible numbers (0-9) and 26 letters in the English Alphabet. Then this means that each character has a total of 36 possible choices. Out of these 36 only 10 are numbers, therefore the probability of the first character being a number is

\frac{10}{36} or 0.2777

If we rounded the decimal to the nearest hundredth it would be 0.28
