Answer:
7.4162
Step-by-step explanation:
Class A: 3 out of 30 = 3 / 30 = 0.1 = 10%
Class B: 28 out of 40 = 28 /40 = 0.7 = 70%
Class C: 11 out of 28 = 11 / 28 = 0.39 = 39%
Class D: 14 out of 50 = 14 / 50 = 0.28 = 28%
The answer is Class D
The dice could either roll 6 and 5 or 5 and 6 which gives us the probability of 2/36.
1) Find the gradient of the line by using two of the points given.
2) Find the y-intercept by using either one of the points into y=mx+c
3) The eq. is, y=5x-1
