Question
A uniform distribution is a continuous probability distribution for a random variable x between two values a and b (a <b), where a ≤x≤b
and all of the values of x are equally likely to occur. The graph of a uniform distribution is shown to the right. The probability density
function of a uniform distribution is shown below. Show that the probability density function of a uniform distribution satisfies the two
conditions for a probability density function.

Show that the value of the function can never be negative. Choose the correct explanation below.
O A. The numerator of the probability density function is 1, so the function must always be positive.
OB. The denominator of the probability density function is always positive because a <b, so b-a>0, therefore the function must always be positive.
OC. The value of b - a is less than one, therefore the value of the function must always be greater than 1.
