HERE'S AN EXAMPLE OF A PROBLEM THAT YOU COULD SOLVE USING PASCAL'S TRIANGLE. At Pongo McWhiffy's burger bar there are seven items on the menu. Pongo slices open a soggy bun for you and you choose any three different items to go inside. How many different combinations could you have? To work this out you could do a few troublesome sums, but to avoid this you could read the answer right off the Pascal's triangle. Beacause there are 7 items to choose from, you look at the 7th line (which is the line which starts at 1 following by 7)As you can choose any 3 different items, you count inwards from the side. You don't count 1,2,3 but 0,1,2,3, The answer you end up with should be 35.. you can choose 3 different items from a list of seven, and there are 35 different ways you can do this!
