3. (1982 Nov #40 and #41) For a double-decrement table, you are given: (1) 2 (1) + 120 60 + t (ii) Plot 3 120 60+1 (iii) T' is the time-until-decrement random variable for (40). (iv) J is the cause-of-decrement random variable for (40). Calculate the probability that (40) terminates from decrement mode 2. (A) 0.33 (B) 0.40 (C) 0.50 (D) 0.60 (E) 0.67 Calculate fo 7(1 | 10). (A) 0.33 (B) 0.40 (C) 0.50 (D) 0.60 (E) 0.67
