Question

An unbiased die bearing the integers $-2$ to $3$ is thrown once
find the probability that the number drawn is,
A multiple of $3$

Answer 1

The possibilities of outcomes are $6$

$\{-2,-1,0,1,2,3\}$

Probability of getting a multiple of 3,

$\{0,3\}\to 2$

$=1-\frac{6-2}{6}$

$=1-\frac{4}{6}=\frac{1}{3}$

$=0.33$
