1. This answer would be C, n^3 + 5
2. This answer would be D, n^3 + 9
3. This answer would be A, 4n - 11
Add total rolls:
The number of rolls is the height of each bar:
14 + 12 + 16 + 15 + 13 = 70
70 total rolls
The numbers greater than 3 are 4 and 5
4 was rolled 15 times and 5 was rolled 13 times
15 + 14 =28 Total times
The prInability of that happening would be 28/70 which reduces to 2/5
The answer as a fraction is 2/5 which is 40% as a percentage.
6 + 8x, where x is a number. You can also write this in standard form as 8x + 6.
