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.
