If the mode is 3, then we KNOW that y must be 3.
So, the 4 numbers in the list are {4, 6, 3, 3}

What is the average (arithmetic mean) of the list?
Average = (4+6+3+3)/4
= 16/4
= 4

Answer: C

Since 3 is the mode, y must be 3, and the average of the list is 16/4 = 4.

Answer: C

Mode= 3
So, Y must be 3

Average= \(\frac{(4+6+3+3)}{4}\)= \(\frac{16}{4}\)= 4
