If random variable X : waiting time in minutes for bus and probability distribution function of X : is given by f x = 1 5 , 0 ≤ x ≤ 5 0 , o t h e r w i s e Then probability of waiting time not more than 4 minutes is = _______

Options

  1. A0.3
  2. B0.8
  3. C0.2
  4. D0.5

Correct answer

B. 0.8

Step-by-step solution

As given, f x = 1 5 , 0 ≤ x ≤ 5 0 , o t h e r w i s e Now, probability of waiting time not more than 4 minutes is = 4 × 1 5 = 0.8
