order doesn't manner ... pear and plum is the same as plum and pear

(6 * 5) / 2 = ?

this result does not count two of the same fruit as a combination
Idk its prob 7
The correct answer is actually 15.

To find the number of combinations, we can use the formula nC2, where n is the number of options and 2 is the number of items we are selecting.

So, nC2 = 6C2 = (6!)/(2!(6-2)!) = (6*5)/(2*1) = 15

Therefore, Susan can choose from 15 different combinations of two fruits at the store.
