Answer 2

Answer:

The number of different possible meals of 4 items that can be made are found to be 15.

Step-by-step explanation:

We are given a total of 6 items and we have to find the total number of different meal of 4 items that we can make out of these 6 items.

We know, if we have to find the total number of possible combinations that we can make, we use the formula of combinations that is given as follows:

$^nC_r=\frac{n!}{r!(n-r)!}$

where, $n$ is the total number of options available and $r$ is the number of options required.

Here, we are given: $n=6$,

and $r=4$,

Substituting these in the formula, we get:

$^6C_4=\frac{6!}{4!(6-4)!}$

$^6C_4=\frac{6\times 5\times 4!}{4!2!}$

Simplifying it, we get:

$^6C_4=\frac{6\times 5}{2}$

or we can say:

$^6C_4=15$

Thus, there are 15 possible meals of 4 items that can be made out of a total of 6 items.
