Question

You roll a standard number cube. Find P(odd).
1/3
1/2
5/6
2/3

Answer 1

A standard number cube (die) has 6 faces, numbered from 1 to 6. The odd numbers on a die are 1, 3, and 5.

There are 3 odd numbers out of a total of 6 possible outcomes.

So, the probability \( P(\text{odd}) \) is calculated as follows:

\[ P(\text{odd}) = \frac{\text{Number of odd outcomes}}{\text{Total outcomes}} = \frac{3}{6} = \frac{1}{2} \]

Therefore, the answer is \( \frac{1}{2} \).
