Question

What is the approximate probability of Express A arriving at the station after 12:30 hours? *​

Answer 1

Answer:

If angular position time relation for a particle is given by theta = 2t ^3 + 5 t ^2 + 3 then calculate average angular acceleration for time interval t = 0 sec to t = 2 sec

Answer 2

The approximate probability is 0.44 or 44%

Explanation:

• We are given that a train is on-time ONLY IF it arrives on or before the scheduled arrival time
• Therefore $n(journeys)-n(on-time) = n(after\ scheduled\ time)$
• Therefore the number of times Train A has arrived After 12:30 is $134 - 75 = 59$ times
• therefore the probability of train A arriving after 1230 hrs is

                                   $59/134 = 0.44029 \approx 0.44$

• Hence the required probability is 0.44
