Question 1133543
<br>
Since it is significant whether a member is selected as a delegate or an alternate, there are...<br>
10*9 = 90 ways to choose 2 of the 10;
7*6 = 42 ways to choose 2 of the 7; and
8*7 = 56 ways to choose 2 of the 8.<br>
The total number of ways of selecting a delegate and an alternate from each of the three groups is the PRODUCT of those three numbers:<br>
90*42*56 = 211680
