Hi I need help with my homework I am unsure if they are correct.
1) In California, car license plates are made up of one digit, 3 letters and then 3 digits. for example 3 GTW 832. its not true but assume that all numbers and letters could be used.
A) how many possible license plates are there in California?
I have concluded that 26 letters and 10 numbers = 35 thus making it 37^7 = 7.84641641E10 is this correct?
If so can would the 2nd problem have the similar approach? ,
B) a witness to a crime saw the license plate of the getaway car, she said it started out with 3 TKY. how many cars in California can have this? what percentage of all license plates in California start with 3 tky?
again 26 letters and 10 numbers=35 making this problem 35^4 = 1500625 ? but how would I find the percentage
