Which of the following cannot be valid assignment of probabilities for outcomes of sample space `S = {omega_(1), omega_(2), omega_(3), omega_(4), omega_(5), omega_(6), omega_(7)}`?

Explanation

Concept : for valid assignment , sum of all possibilities of each assignment should be 1 .


(a) sum of all possibilities = `0.1 + 0.01 + 0.05 + 0.03 + 0.01 + 0.2 + 0.6 = 1`

Hence, the assignment is valid .


(b) sum of all possibilities = `1/7 + 1/7 + 1/7 + 1/7 + 1/7 + 1/7 + 1/7 = 7/7 = 1`

Hence, the assignment is valid.
