Suppose a uniform random variable can be used to describe the outcome of an experiment with the outcomes ranging from 50 to 80.

taurus [48]

Answer:

The correct answer is $\frac{1}{3}$ = 0.33.

Step-by-step explanation:

A uniform random variable is used to describe the outcome of an experiment with the parameters being 50 and 80.

Probability density function = f(x) = $\left \{ {{\frac{1}{b-a} , a$

Here a = 50 and b = 80.

We need to find the value of probability of this given experiment in an outcome less than 60.

∴ P(X<60) = $\frac{60-50}{80-50} = \frac{10}{30} = \frac{1}{3}$ = 0.33.

Thus the required probability is given by 0.33.
