In a discrete random variable x follows uniform distribution and assum...
Explanation:
Given, x follows a uniform distribution and takes values 8, 9, 11, 15, 18, 20.
As x follows a uniform distribution, each value has an equal probability of occurring.
Hence, P(x = 8) = P(x = 9) = P(x = 11) = P(x = 15) = P(x = 18) = P(x = 20) = 1/6.
As 12 is not one of the values that x can take, P(x = 12) = 0.
Therefore, option B is the correct answer.
Answer: B) 0
