<p>G.) how many distinct license plates can be issued with 2 letters followed by 3 digit numbers?</p>
<p>H.) how many 3 letter codes can be formed using the letters A B C D and F? Repeated letters are allowed.</p>
<p>A) Answer: 6/21 * 5/20 * 4/19 = 2/133
B) 1/36
C) 34/52 (if the Ace is a face card)
D) 2/52
E) 9/10
F) 9! = 362,880
G) 26<em>26</em>10<em>10</em>10 = 676,000
H) 5C3 * (5^3) = 1250</p>
<p>Please let me know if I got any wrong or if you’d like me to explain any of the answers.</p>
<p>I think H) is just 5x5x5=125.</p>
<p>For C) I don’t think that Aces are face cards so my answer is 32/52.</p>
