The probability of rolling a 2 on a number cube is 1/6 . If you were to roll the cube 30 times, you would expect to get a 2 around 5 times ( 1/6 .30= 5) You simulate 30 rolls. How many 2s would make you question your model? A. 5

B. 14

C. 2

D. 8

If the ratio of sum of the first m and n terms of an ap is m2 : n2 , show that the ratio of its mth and nth terms is (2m − 1) : (2n − 1).
