In a certain communications system, there is an average of 1 transmission error per 10 seconds. Let the distribution of transmission errors be Poisson. (97) The probability of more than 1 error in a communication one-half minute in duration is about (A) 0.950 (B) 0.262 (C) 0.738 (D) 0.199 Statistics and Probability - m Final Exa 2020 - Second Term 2019 - year nd 2 . Fac. Of Engineering (Girls) - Azhar Unv. - Al Page 10 of 12 (98) The probability that there is exactly 2 transmission error per 10 seconds is about (A) 0.184 (B) 0.457 (C) 0.025 (D) 0.958 (99) The probability that there is at most 2 transmission errors per 10 seconds equals: (A) 0 (B) 0.9197 (C) 0.258 (D) 0.025 (100) The average number of transmission errors per one minute equals: (A) 4 (B) 6 (C) 1 (D) 20 (101) The variance of transmission errors per one minute equals: (A) 4 (B) 6 (C) 1 (D) 20
