Probability Review

Baylee will roll a number cube and flip a coin for a probability experiment. The faces of the number cube are labeled 1-6. The coin can land on heads or tails. If Baylee rolls the number cube once and flips the coin once, which list contains only the outcomes in which the number cube lands on a number greater than 4?

  5, Tails

  6, Heads

A number cube with faces labeled from 1 to 6 was rolled 20 times. Each time the number cube was rolled, the number showing on the top face was recorded. The table shows the results. Based on these results, what is the experimental probability that the next time the number cube is rolled it will land with 5 or 6 showing on the top face?
