Answer:
60.
Step-by-step explanation:
This is a permutation exercise because order matters. The formula is n!/(n-r)!. In this case n=5 and r=3 so,
5!/(5-3)! = 5!/2! = 5!/2 = (5*4*3*2*1)/2 we can simplify the 2 and obtain 5*4*3= 60.
Pretty sure it d.12 bc you were counting from 3’s so the next number up would be 12

2 * 3 = 6 (BC and EF)
However...
2 * 3 = 6 not 7 (AC and DF)
