Answer 1

Given the following question:

Clermont - Ferrand

15 letters in total

Three R's in the 15 letters

15 - 3 = 12

12 possible letters we can receive

$\begin{gathered} \frac{12}{15} \\ \text{ Simplify} \\ \frac{12}{15}\div3=\frac{4}{5} \\ =\frac{4}{5} \\ \frac{4}{5}=4\div5=0.8 \end{gathered}$

Simplfied fraction = 4/5

Decimal = 0.8
