Answer:
A) 6
Step-by-step explanation:
To find the number of combinations for selecting 2 items from a set of 4 items, we can use the formula for combinations:
nCr = n! / (r! · (n-r)!)
Where:
n = the total number of items
r = the number of items we are selecting
In this case:
n = 4
r = 2
Plugging this into the formula:
4C2 = 4! / (2! · (4-2)!)
= 4! / (2! · 2!)
= 24 / (4 · 2)
= 6
So, there are 6 possible combinations for selecting 2 items from a set of 4 items.
