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:

Using Sue's simulation, what is the probability of rolling a 2 on the number cube and the coin landing heads up?
(5 points)
Group of answer choices
56 over 100
1100 over 10000
1400 over 10000
81 over 100
The total number of times Sue rolled the number cube and flipped the coin is 100.
From the table:
- The number 2 was rolled 25 times.
- Heads came up 56 times.
The probability of rolling a 2 and the coin landing heads up is the number of times both events happened divided by the total number of times the experiment was run:
Probability = (Number of times both events happened) / (Total number of trials)
Probability = (25 + 56) / 100 = 81/100
Therefore, the probability of rolling a 2 on the number cube and the coin landing heads up is 81 over 100.
