The probability of an operator entering alphanumeric data incorrectly into a field in a database is equally likely. The random variable X is the number of fields on a data entry form with an error. The data entry form has 28 fields. Is X a discrete uniform random variable? Why or why not? (Please provide the mathematical details that lead to your answer.)

Since P(0) and P(1) have not the same values for the probability, X is not a discrete uniform random variable.

Step-by-step explanation:

Probability of data to be correct: 0.5

Probability of data being incorrect: 0.5

The random variable X is the number of fields that have an error within the range of 28.

P(0) =

P(1) =

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
