A is (1, –2) and B is (3, 6). a. Find the length of AB.
b. Find the mid-point of AB.
c. Find the equation of the perpendicular
bisector of AB.

I know mid point is (2,2)

Step-by-step explanation:

Chance of getting number greater than 4 on one roll:

Either getting a 5 or 6

2/6 probability

2/6 = 1/3

If we roll the cube 12 times, the probability of getting a number greater than 4 is 1/3 of the time

12 * 1/3 = 4

She is expected to get a number greater than 4, 4 times
