alicia rolls two fair number cubes numbered from 1 to 6. she first defines the sample space, as shown below:
(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6)
(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6)
(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6)
(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6)
(5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6)
(6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)
based on the sample space, what is the probability of getting a total of 7?
4 over 36
5 over 36
6 over 36
8 over 36

the number of chips of different colors in gail's bag is shown below:
•3 blue chips
•4 pink chips
•8 white chips
gail takes out a chip from the bag randomly without looking. she replaces the chip and then takes out another chip from the bag. what is the probability that gail takes out a white chip in both draws?
8 over 15 multiplied by 7 over 14 is equal to 56 over 210
8 over 15 plus 7 over 14 is equal to 217 over 210
8 over 15 plus 8 over 15 is equal to 16 over 15
8 over 15 multiplied by 8 over 15 is equal to 64 over 225
sue used a probability simulator to roll a 6-sided number cube and flip a coin 100 times. the results are shown in the tables below:
number on cube vs number of times rolled
1 18
2 25
3 12
4 32
5 3
6 10
heads = 56
tails = 44
using sue's simulation, what is the probability of rolling a 2 on the number cube and the coin landing heads up?
81 over 100
56 over 100
1400 over 1
1100 over 1
