Question

Which would be included in a probability model for rolling a cube with faces numbered 1 through 6. Select all that apply. A. Sample space 1,2,3,4,5,6 B. P(1) = 1/6 C. P(2) = 2/6 D. P(6) = 1/6 E. The outcomes of the trial: 2, 2, 2, 5, 3, 2, 6, 5, 6, 1

Answer 1

A,B, D and E.

Explanation:

When a cube with faces numbered 1 through 6 is rolled:

(A)The sample space is 1,2,3,4,5,6. Option A is correct

(B) P(rolling a 1) =1/6, Option B is correct

(C)P(rolling a 2)=1/6, therefore option C is incorrect.

(D)P(rolling a 6)=1/6, Option D is correct

(E)In an experimental trial, the outcome must be members of the sample space. Therefore, the outcomes in option (E), 2, 2, 2, 5, 3, 2, 6, 5, 6, 1 are valid.

Options A,B, D and E would be included in the probability model.
