Question

The probability of rolling a 2 on a number cube is 1/6 . If you were to roll the
cube 30 times, you would expect to get a 2 around 5 times (1/6 · 30 = 5).
You simulate 30 rolls. How many 2s would make you question your model?

A. 14
B. 5
C. 2.
D. 8

Answer 1

Answer: a

Step-by-step explanation:

Answer 2

If a cube is rolled by 30 times then 5 times 2s will make the question the model.

What is probability?

Probability is the occurrence of any event or how likely an event can happen.

Mathematically probability = the number of desired outputs by the number of the possible outcomes.

In the number cube, there are six faces above each of them written one to six later.

The probability of getting 2 at once time will be 1/6 since the number of desired output is only one and possible outcomes are six.

Mathematically(Theoretically) if we roll the cube 30 times then the number of 2s will be 1/6 × 30 = 5 times.

If experimentally if we roll dice and the number of 2s came 5 times then our question will become a model.

So by 5 times, 2s will make the question model.
