3. A number cube is marked with 1, 2, 3, 4, 5, and 6 on its faces. If you roll the
cube one time, what is P(2)
•
A) 1/3
B) %
C) 2
D) 1/6

Answer 1

Option D).
`(1)/(6)`

Explanation:

Total number of faces on cube marked with 1 to 6 respectively = 6

If the cube is rolled once then probability of getting one face,

P =
`\frac{\text{Favorable outcome}}{\text{Total number of possible outcomes}}`

Favorable outcome = getting the face marked with number 2 = 1

Total number of possible outcomes = Getting all faces once = 6

So probability to get a face marked with number 2,

P(2) =
`(1)/(6)`

Therefore, option (D) is the answer.
