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
If Susan is at the store and can buy any two fruits (the store sells apples, oranges, pears, bananas, plums and kiwis), how many combinations of fruit can she choose?

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.
