Question

Find the theoretical probability of the event when rolling a standard number cube. P(5)

Answer 1

A standard number cube is a die.

The sample space or total number of possible outcomes for a die is six(6).

Probability of an event, say E, is given mathematically as:

$P(E)=\frac{\text{number of favourable outcome}}{\text{Sample space}}$

Hence, the probability of obtaining a 5 is:

$P(5)=\frac{1}{6}=0.167$
