Question

PLEASE WRITE A PROGRAM IN MATLAB FOR THE FOLLOWING:

Probability Practice Simulating the Horse Races Four horses (A, B, C, and D) have raced many ti mes. It is estimated that A wins 30 percent of t he time, B wins 40 percent of the time, C 20 p ercent of the time, and D10 percent of the tim * Simulate the outcomes of n races. Run this pro gram for n- 10, 100, and 1000. Plot the results

Answer 1

SOLUTION

Awin=0;
Bwin=0;
Cwin=0;
Dwin=0;
ran=[10,100,1000];
for i=ran
Awin=[Awin;i*0.3];
Bwin=[Bwin;i*0.4];
Cwin=[Cwin;i*0.2];
Dwin=[Dwin;i*0.1];
endfor
ran=[0,ran]
plot (ran,Awin,ran,Bwin,ran,Cwin,ran,Dwin);
xlabel ("Total Races");
ylabel ("Won Races");
legend('Horse-1','Horse-2','Horse-3','Horse-4');
title ("HORSE-RACE PLOT");

HORSE-RACE PLOT 400 Horsa-1 -Horse-2 Horsa-3 -Horse-4 300 뜨 200 100 200 400 600 800 1000 Total Races

Here Awin , Bwin , Cwin & Dwin stores the number of winning races by respective horses (A,B,C & D).

Awin=[Awin;i*0.3] => since the winning of horse A is 30% therefore it can also be written as :

(Number of Matches x 30) /100 =Number of Wins of Horse A.

Therefore we can also right it as : (Number of Matches x 0.3) = Number of Wins of Horse A.

here in the loop number of matches is determined by i , this is how this statement calculates the winning matches.

Hope this helps. If you like the answer please rate it.

Thanks!
