Count the possible combinations of r letters chosen from the given list P.Q,R,S,T,U; r = 2
Tasya [4]

Answer:

<h2>There are 30 possible combinations of picking two letters.</h2>

Step-by-step explanation:

The combinations are defined as

C^{r}_{n}=\frac{n!}{(n-r)!}

Where n is the total number of elements and r is the number of letter we are gonna picke, which is two. Using this information, we have

C^{2}_{6}=\frac{6!}{(6-2)!}=\frac{6!}{4!}=\frac{6 \times 5 \times 4!}{4!}=30

Therefore, there are 30 possible combinations of picking two letters.
