Question

Suppose you roll a cube 30 times, what is a to describe the theoretical of rolling a 1, 4, 6, 7 Please help me!

Answer 1

`Pr(x) = (1)/(6)`

Explanation:

Given

`n = 30` --- number of rolls

Required

The theoretical probability of rolling: (a) 1 (b) 4 (c) 6 (d) 7

Assume the cube is 6 sided.

The sample space is:

`S = \{1,2,3,4,5,6\}`

And the probability of each is:

`Pr(x) = (1)/(6)`

Irrespective of the number of rolls, the theoretical probability of (a). (b), (c) and (d) is:

`Pr(x) = (1)/(6)`
