Question

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 = _______, 0.3, 0.8, 0.2, 0.5

MARKS App · Accepted Answer

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
