Question

Liang has five balloons that are identical, except for their colour. Three are red (each labelled with an R) and two are green (each labelled with a G). He wants to put the five balloons in a row, but he is not sure which order he likes the best. How many different ways are there to arrange the five balloons in a row?
And please dont say some random answer or scam link.​

Answer 1

Using the arrangements formula, it is found that there are 10 different ways to arrange the five balloons in a row.

What is the arrangements formula?

The number of possible arrangements of n elements is the factorial of n, that is:

$A_n = n!$

When elements repeat $n_1, n_2, \cdots n_n$ times, we have that:

$A_n^{n_1, n_2, \cdots, n_n} = \frac{n!}{n_1!n_2! \cdots n_n!}$

In this problem, 5 elements, repeating 3 and 2 times, hence:

$A_5^{3,2} = \frac{5!}{3!2!} = 10$

There are 10 different ways to arrange the five balloons in a row.
