Question

A fair dice is rolled . work out the probability of getting a factor of 8 Give your answer in it's simplest form

Answer 1

Answer:

$Pr = \frac{1}{2}$

Step-by-step explanation:

Given

$S = \{1,2,3,4,5,6\}$ --- the faces of the dice

$n(S) = 6$

Required

Pr(Multiple of 8)

The multiples of 8 in the given dataset are:

$Multiples = \{1.,2,4\}$

$n(Multiples) = 3$

So, we have:

$Pr = \frac{n(Multiples)}{n(S)}$

$Pr = \frac{3}{6}$

Simplify

$Pr = \frac{1}{2}$
