Math Question: A triangle ABC is drawn on a plane and a ball is placed on vertex A. A dice is rolled, and the ball is moved according to the following rules: i) when the ball is on A, if the number on the dice is 1 the ball is moved to B,otherwise it stays on A ii) when the ball is on B, if the number on the dice is less than or equal to 4 the ball is moved to C, otherwise it stays on B. If the ball is moved to C,the trials are stopped We are to find the probability that the ball is moved to C within 4 rolls of the dice Q1) The probability that the ball is moved to C on the second roll of the dice is 1/N Q2) The probability that the ball is moved to C on the third roll of the dice is O/PQ Q3) The probability that the ball is moved to C on the fourth roll of the dice is RS/TUV Therefore,the probability that the ball is moved to C within 4 rolls of the dice is WX/YZ (The way to answer the question is to type what number is the alphabets) (Ps.After solving the question, can you link a website or a pdf note that teaches you about the subject of the question. Thanks !!)
