Question

The numbers 1 to 12 inclusive are
placed in a hat. John takes a
number out of the bag at random.
What is the probability it is a 5?

Answer 1

There are 12 numbers 1 to 12

So, probability of 5 is 1/12

Answer 2

$\pink { Number \:of \: total \: possible \: outcomes}$

$= Numbers \: placed \: in \:a \:hat$

$= 12 \: --(1)$

$Favourable\:outcomes$

$= \{ 5\}$

$\blue { Number \:of \: favourable \: outcomes} = 1\:--(2)$

$\orange { Probability ( getting \: number \:5)}$

$= \frac{(2)}{(1)}$

$= \frac{1}{12}$

Therefore.,

$\red{ Probability ( getting \: number\:5 )}\green { =\frac{1}{12}}$
