The probability that it will get to b within 7 hours is approximately 0.014.
Probability:
In math, the favorable way of happening the event is known as probability.
Given,
A frog starts at location a and wants to get to location b that is 500 meters away. starting at a, it sits at a given spot on the path from a to b for a time that is exponentially distributed with parameter 1 (minute). after that, it jumps 1 meter towards b, sits in the new spot for an exponentially distributed time, etc. all the times are independent.
Here we need to find the the probability (approximately) that it will get to b within 7 hours.
While we looking at the given question we have identified that,
starting point = a
ending point = b ( 500 meters)
Time take for one jump = 1 minute
Distance covered in one jump = 1 meter.
Here they also said that the time is independent but the distance remains constant.
So, the probability that it will get to b within 7 hours is calculated as,
=> 7/500
=> 0.014
