Simulate how many steps its take a random walker starting at the center of an 10x10 grid to visit every cell of the grid. If the walker tries to go outside of the grid then it doesn't move in that step. Write a java program which simulates th steps of the random walker, and keeps hold about the grid with 2D boolean array and write out the steps when the random walker have walked all the cells. ----------------------------------------------------------------------------------------------- I have...

4. Suppose we roll N dice, where N is a random number, with P ( N = i ) = 2 − i for i ≥ 1 . The sum of the dice is denoted by S . Find the probability that: (a) (5 points) N = 2 given S = 4 ; (b) (5 points) N is even; (c) (5 points) S = 4 given N is even.
Problem 7. Consider a robot taking a random walk on the integer line. The robot starts at zero at time zero. After that, between any two consecutive integer times, the robot takes a unit length left step or right step, with each possibility having probability one half. Let F denote the event that the robot is at zero at time eight, and let X denote the location of the robot at time four (a) Find P(F). (b) Find the pmf...

1. Two random walkers start out together at the origin, each having equal probability of making a step to the left or right along the r axis. Find the probability that they meet after N steps. (They take their steps simultaneously. It may be helpful to consider their relative motion.)
Write a simulation of zombies/walkers that move randomly in one dimension. Each walker begins at the origin and at each time-step it takes a step to the right or left with equal probability, so that Pright= 0.5, Pleft= 0.5. Use a lattice of spacing x =1 and discrete time-steps, t= 1. Number of steps in each walk: 20 Number of walkers: 10.000 Please make your own algorithm for this simulation. Note: You will need to use a random number generator....
A particle executes a simple unrestricted random walk on the line: a step to the right of length 1 occurs with probability 0 56 and a step to the left of length l occurs with probability 0 44 Initially the particle is at the origin. Select the option that gives an approximate value for the probability that the particle will be less than 6 units from the origin after 100 steps, calculated using an appropriate continuity correction Select one: 0.195...
