<p>Could anyone explain to me the word problem in page 465 number 8 ... the one about meredith ... i can't understand how the answer is 6 ... it should be 3 because she will wear a "one" color outfit everytime ... a day she will wear a red hat,sweater and trousers and a day she will wear a white hat,sweater and trousers ... Etc.</p>
<p>She wants to wear an outfit with 3 different colors each time.
So the answer is 3! = 3 x 2 x 1
Because for example;
Hats: she has three to choose from, say she chooses a red hat
Sweater: she has 2 to choose from (can’t pick red), say she chooses white
Trousers: she can only pick the blue one
So the answer is 6</p>
