A mini license plate for a toy car must consist of a vowel followed by two numbers. Each number must be a 3 or 7. Repetition of digits is permitted.
�Use the counting principle to determine the number of points in the sample space.
pick a vowel: 5 ways
pick a number: 2 ways
pick a number: 2 ways
===
# of points in the sample space = 5*2*2 = 20
------
�Construct a tree diagram to represent this situation and submit it to the
�List the sample space.
a33,a37,a73,a77
Same pattern with e,i,o,u
-----------------------------------
�Determine the exact probability of creating a mini license plate with an A.
Give solution exactly in reduced fraction form.
Ans: 4/20 = 1/5
