Question

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.

Number Showing on Top Face Frequency
1 0
2 3
3 3
4 6
5 3
6 5


If you were to use these results to predict the probability of the next number showing on the top face, what type of probability would you be using?



A) Theoretical probability

B) Experimental probability

C) Independent probability

D) Dependent probability

Answer 1

Option B, Experiment probability has to be used to predict the probability of the next number showing on the top face.

Explanation:

Theoretical probability : Theoretical probaility is the value expected from an outcome or an equation assuming perfect conditions. It is based on theories and hypotheisi and not based on real life incidents.

Experimental probability : When we performa n experiment, the values we get are experimental probability. These are actual rsults of the eperiemnt under study

Independent probability : Two events A and B are said to be independent if the fact that one event has occurred does not affect the probability that the other event will occur.

Dependent probability: If whether or not one event occurs does affect the probability that the other event will occur, then the two events are said to be dependent.

Since the results of the experiment are used and based on the above definitions. we should use experiement probabiity (Option B) to predict he probability of the next number showing on the top face
