D. 6
Step-by-step explanation:
The result of 20 rolls in given in the statement we have to find how many times did the roll resulted in a result greater than the average number. So first we have to find the average of the 20 rolls.
The formula for the average is:
So, the formula for the given case will be:
Thus, the average result from the 20 rolls is 3. Now we have to look for values greater than 3 in the rolls. These are:
6, 4, 5, 4, 5, 6
So, 6 values in total are greater than 3.
Hence, Gabe rolled 6 times above average.
