Group of answer choices

56 over 100

1100 over 10000

1400 over 10000

81 over 100

Answer 1

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.
