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) =

Sam sold half as many as Odel.
That means Odel sold twice as many as Sam.
Let x = number of pizzas sold by Sam.
Then Odel sold 2x.

x + 2x = 126
3x = 126
x = 42
Since x is the number of pizzas sold by Sam, that is our answer.
Answer: Sam sold 42 pizzas.
