Answer 2

0.28

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

`(10)/(36)` or 0.2777

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