You can put this solution on YOUR website! 1. One card is selected at random from a deck of cards. Find the probablity that the card is a red OR a 10
---
P(red OR 10) = P(red) + P(10) - P(red AND 10)
= 26/52 + 4/52 - 2/52
----
= 28/52 = 7/13
-----------------------------
2. A license plate is to contain 3 letters followed by 3 digits. If the first letter can't be X or Z, and repetition is permitted, fnd the number of license plates possible.

# = 24*26^2*10^3 = 16,224,000
