Step-by-step explanation:
If he rolled the dice 50 times and got the following result
Sum of the number-Number of rolls
2-1
3-4
4-3
5-6
6-7
7-10
8-7
9-5
10-4
11-2
12-1
What percentage of the rolls resulted in a sum of 7?
Percentage of the rolls that resulted in a sum of 7 = 100% × (number of times the sum of 7 showed up)/(total number of rolls)
From the data presented above,
number of times the sum of 7 showed up = 10
total number of rolls = 50
Percentage of the rolls that resulted in a sum of 7 = 100% × (10/50) = 20%
