Question

Ethan rolls a 6-sided number cube. What is the probability that he gets a number less than 3?

Answer 1

We have been given that Ethan rolls a 6-sided number cube. Then, the sample space is S={1, 2, 3, 4, 5, 6}

n(S) = 6

Let E be the event of getting a number less than 3.

Then, E = {1, 2}

n(E) = 2

Probability of an event is given by $\frac{n(E)}{n(S)}$

$= \frac{2}{6}$

$= \frac{1}{3}$

Hence, the probability that Ethan gets a number less than 3 is $\frac{1}{3}$.
