Re: Who likes math?
there are ten different 1st digits (0-9), ten different 2nd digits, and ten different 3rd digits. how many different combinations of digits are there if you must select one of each group of digits to make a 3 digit number?
i counted to 156 from 000 when i got tired of counting. i'll never make it to 999 and find out the answer. |

I came up with 144 the first time I did it. But since they can only choose one of each book I thought it was wrong. For instance isn't 2 statistics books and 1 geometry book one of the possibilities of the 144? [/ QUOTE ] No, it's not. |

Re: Who likes math?
Suppose I have 1 book A and 1 book B. How many combinations are there if I select 1 of each type?
1 * 1 = 1 Suppose I have 2 Book A and 2 book B. How many combos, once again selecting 1 of each? 2 * 2 = 4 Thats how you do these sorts of problems. What are they teaching you guys in school nowadays, anyways? |
