In how many ways can you spell the word FOOT in the grid below? You can start on any letter F, then on each step you can step on
muminat

There are six ways in which the word FOOT may be spelt starting at any letter.

<h3>What is combination?</h3>

The term combianntion offers a plausible way to carry out a selection as long as we do not give preference to the order in which the selection is made. In this case, we are told that we can start from any letter therefore order is not important.

There are four letters in FOOT and one letter is repeated twice therefore;

4C2 = 4!/(4-2)! 2!

4C2 = 4 * 3 * 2!/2! * 2 *  1

4C2 = 12/2

4C2 = 6
