The experimental probaility of a "1" on the next roll is
245 / 1230 =
.1992 ⇒ B
Note something, NSS.....this isn't the theoretical probability....past outcomes have no effect on the next roll in the theoretical pobability because these are independent events.....thus the theoretical probability of rolling a "1" on the next roll is still 1/6 = .1667 !!!!
