1) Two cards are drawn from a standard deck and one of the two cards is noted and removed. Find the probabilities of the second card.
P(queen|five) = 4/51
----------
P(red/red)= 25/51
----------
2) Suppose that you toss a coin and roll a die. What is the probability of obtaining each of the following combinations? (Enter your answers as fractions.)
P(tails and an odd number) = (1/2)(1/2) = 1/4

4 combos: 1/3 ; 2/2 ; 3/1
5 combos: 1/4 ; 2/3 ; 3/2 ; 4/1
---
P(4 or 5) = 7/36
===============================
4) What is the probability of getting a license plate that has a repeated letter or digit if you live in a state that has one letter followed by two numerals followed by six letters? (Round to the nearest whole percent.)
Ans: 1 - P(no repeated letter or digit)
= 1 - (26*10*9)/[26*10^2]
---
= 1 - [9/10]
----
= 1/10
==========================
5) What are the odds in favor of drawing face card from an ordinary deck of cards?
ans: odds infavor of = P(for)/P(against)
= (12/52)/(40/52)
= 12:40
