Which is the probability of rolling an odd number on a fair 6-sided number cube.
1, 1/6, 5/6, 1/2

Solution:

Given the number of sides on the dice = 6

Sample space = {1, 2, 3, 4, 5, 6}

Total outcomes = n(S) = 6

Let A be the event of odd numbers

A= {1, 3, 5}

Favorable outcomes = n(A) = 3

P(A) =Favorable outcomes/Total outcomes

=n(A)/n(S)

=3/6

= 1/2

Therefore, the probability is 1/2.

Which is the probability of rolling an odd number on a fair 6-sided number cube.

Summary:

The probability of rolling an odd number on a fair 6-sided number cube is 1/2.
