Since there are two identical gift cards, it doesn't matter who gets the first gift card and who gets the second gift card, so this is a combination
There are 5 people choose 2
n!
--------
r!(n − r)!
where n is the number of items and r is how many we choose
5! 5*4*3*2*1
-------- = ------------------ = 10
2! (5-2)! 2*1 ( 3*2*1)
D.

answer : D
A. (6 × 7) + 6 = 48
Associative property of multiplication . Here we have +6 . there is a + sign inbetween. so it does not comes under Associative property of multiplication
B. 6 × (4 + 2) = 36
Here we have 4 +2 . there is a + sign inbetween. so it does not comes under Associative property of multiplication
C. (6 + 4) × 2 = 20
Here we have 6 + 4 . there is a + sign inbetween. so it does not comes under Associative property of multiplication
D. (6 × 4) × 2 = 48
Here we have 6 times 4 times 2. so it comes under Associative property of multiplication
