Explanation / Answer

Q.6 (a) Probability that he or she satisfied with student government = Total satisfied students/ Total students

= 234/370 = 0.632

(B) Probability that he or she is a junior = Total junior/ Total students = 94/ 370 = 0.254

(C) Probability that he/ she is a satisfied Junior = 67/ 370 = 0.181

(D) Probability that he/ she satisfied or junior

so total number of satisfied person = 234

total number of junior = 94

total number of satisfied and junior both = 67

so number of satisfied or junior = (234 + 94 - 67)/ 370 = 0.705
