A self driving car makes a forbidden U-turn and a regular car crashes against it. Three witnesses, whom we call Bison, Rabindranath, and Tom saw what happened. Suppose the reliability of the witnesses is estimated by having the witnesses observe a number of similar scenes. It is found that Bison has probability 0.9 of stating that the self-driving car did a forbidden U- turn, Rabindranath has probability 0.8 of stating that, and Tom has probability 0.7 of stating that. Let A, B, and C denote, respectively, the events that persons Bison, Rabindranath and Tom will state that the self driving car did the forbidden U-turn. Assuming that these events are independent events, calculate the probability that all three witnesses will testify that the self-driving car did the forbidden U-turn.
