A.
toss a coin one time

B.
spin a spinner with 4 equal sections one time

C.
roll a six-sided number cube one time

D.
pick a card from 10 cards one time

Answer 2

D. Experimental probability

C. Roll a six-sided number cube one time.

Explanation:

In the first sentence, we talk about experimental probability. Experimental probability refers to the ratio of the number of times an event occurs to the number of times an activity is performed. In this case, the number of times an event occured was 16, while the number of times the activity was performed was 30. Therefore, the ratio is 16:30.

In the second example, the number of children is six, and only one of them will be able to get the shortest straw. This means that we need a single random result out of a pool of six. This is similar to rolling a six-sided number cub once.
