You can put this solution on YOUR website! A mini license plate for a toy car must consist of a letter followed by two numbers.
Pattern: LNN
-------------------------
Each letter must be a B, C or D. Each number must be a 5 or 6. Repetition of digits is permitted.
Use the counting principle to determine the number of points in the sample space.
Ans: 3*2*2 = 12
---------------------------------
Construct a tree diagram to represent this situation
List the sample space.
B55,B56,B65,B66,C55,C56,C65,C66,D55,D56,D65,D66
---------------------------------------
Determine the exact probability of creating a mini license plate with a B. Give solution exactly in reduced fraction form.
Ans: 4/12 = 1/3
