a. Of getting a 4
P(4) = 1/6
b. Of getting an even number
P(even #) = 3/6 = 1/2
c. Of getting a number greater than 4
P(>4) = 2/6 = 1/3
d. Of getting a number less than 7
P(<7) = 6/6 = 1
e. Of getting a number greater than 0
P(>0) = 6/6 = 1
f. Of getting a number greater than 3 or an odd number
P(>3 or odd #) = 4/6 = 2/3
g. Of getting a number greater than 3 and an odd number
P(>3 & odd #) = 1/6

P(ace of diamonds) 1/52
d. A 4 or a 6
P(4 or 6) = 8/52 = 2/13
e. A 4 or a club
P(4 or club) = 16/52 = 4/13
f. A 6 or a spade
P(6 or spade) = 16/52 = 4/13
g. A heart or a club
P(heart or club) = 26/52 = 1/2
h. A red queen
P(red queen) = 2/52 = 1/26
i. A red card or a 7
P(red card or 7) = 28/52 = 7/13

Rolling a Die
. If a die is rolled one time, find these probabilities.
Drawing a Card
. If one card is drawn from a deck, find the probability of getting these results.
Rural Speed Limits
. Rural speed limits for all 50 state are indicated below
Craps Game

of getting these results.
a. An odd number (Do not count 0 or 00)
P( odd #) = 18/38 = 9/19
b. A number greater than 27
P(>27) = 9/38
c. A number that contains the digit 0
P(# contains 0) = 5/38
d. Based on the answers to parts a, b, and c, which is the most likely to occur? Explain.
An odd number is most likely to occur because 9/19 is just over 47% while the
other two are both less than 25%.
