Question

Let X is a continuous random variable denoting the temperature measured. The range of temperature is [0, 100] degree Celsius and let the probability density function of X be f(x) = 0.01 for 0 ≤ X ≤ 100. The mean of X is __________.

Options :

  1. 2.5

  2. 5.0

  3. 25.0

  4. 50.0

Show Answer

Answer :

50.0

Solution :

Given probability density function of X

f(x) = 0.01 for 0 ≤ X ≤ 100

The mean or expectation of a continuous random variable is given by

E ( x ) = 0 100 x ( 0.01 ) d x = 50
