The mode is a number that is repeated the most, so if there is 3 numbers, the "mode number" has to be repeated twice or three times.
A) since 1 is the mode, two of the numbers are 1, the last number is
15 -1 -1 = 13 the three numbers are 1, 1, and 13.
B) since 5 is the mode, two of the numbers are 5, the last number is
11 -5 -5 = 1 the three numbers are 5, 5, and 1.
Range is when you subtract the smallest number to the biggest number, so 5-1=4 The answer is 4
